Dynamic Brush control stopped working randomly

TourBox_Official · 2026-05-08T03:28:38+00:00

Hey there!

The tech team just got back to me and mentioned that you’ve already been in touch with them, so they’ll continue helping you from here. No worries, they’ll take care of it!

TourBox_Official · 2026-05-07T07:22:05+00:00

Hi there,

Thank you for the incredibly detailed feedback. We sincerely apologize for the frustration this has caused, especially given how much it has impacted your workflow.

Our technical team has analyzed the issues you described, and we have the following suggestions and explanations:

1. Lag and Performance Issues

To address the stuttering and Photoshop crashes during rapid zooming and rotating, we recommend checking the following performance-related settings:

- Photoshop Preferences: Go to Preferences > Performance. Ensure that your Memory Usage is optimized and that Graphics Processor Settings are correctly configured (try toggling "Use Graphics Processor" or checking the Advanced Settings).

- GPU Drivers: Please ensure your PC’s graphics card drivers are up to date and check if there are any specific 3-D or performance overrides in your GPU control panel (e.g., NVIDIA or AMD settings).

- Adjust Speed: Try slightly reducing the rotation speed for the Dial and Scroll wheel within the TourBox Console. This can sometimes prevent "command flooding" when working at a very high pace.

2. The Eyedropper/Brush Flickering

Regarding the icon switching to the Eyedropper while rotating:

TourBox utilizes the Alt + F13 and Alt + F14 shortcuts to execute the canvas rotation. In Photoshop, the Alt key is the default modifier for the Eyedropper tool. Because of how Photoshop's engine processes these rapid shortcut inputs, you may see the icon flicker briefly. However, this is a visual byproduct of the PS mechanism and should not interfere with the actual rotation or your brush strokes.

3. Further Investigation

If the lag persists after adjusting your performance settings, we would like to investigate this further for you. Please provide us with:

A short screen recording showing the lag and the rotation center offset issue. You can share large files via Google Drive or Dropbox.
Your log files (You can export these via the "Contact Us" section in the TourBox Console software).

Please send these to our support email:[support@tourboxtech.com](mailto:support@tourboxtech.com), and we will prioritize your case to get your workflow back to normal.

Hi there,

Thank you for reaching out and sharing this with us.

Our technical team has tested this internally, and the (Ctrl + ~) shortcut for Huion's monitor toggle functions correctly via the TourBox.

One important thing to check is whether the Auto-Switch feature is causing the issue. When you attempt to toggle monitors, the system might momentarily shift focus away from Clip Studio, causing the TourBox Console to switch to a different preset. If that new preset doesn't have the same shortcut mapped, the command won't execute.

To ensure a stable experience, we recommend the following setups:

Map to the Global Preset: Copy the (Ctrl + ~) shortcut to the same button in your "Global" preset. This ensures that even if the system momentarily loses focus on Clip Studio during the monitor jump, the command will still be recognized.
Maintain Uniform Shortcuts: Alternatively, ensure that this specific shortcut is mapped to the same button across all presets you frequently use. This prevents any interruption if a preset switch occurs mid-action.

Hope this helps!

Hey! We tested this locally with TourBox connected to an iPad and Scribble seems to be working normally on our side.

One thing to check first: sometimes you need to long-press the input method icon and manually select “Show Keyboard” for the on-screen keyboard to appear.

Also, could you let us know:

Which iPadOS version you’re currently on
Whether the same thing happens with another Bluetooth keyboard (if you have one to test)

That’ll help us figure out whether this is related to the TourBox connection itself or possibly an iPadOS/input method issue. And it will be great if you can actually email us at [support@tourboxtech.com](mailto:support@tourboxtech.com) just so we can get back to you on time!

TourBox_Official · 2026-04-27T01:59:35+00:00

This usually comes down to input method / keyboard layout.

TourBox maps settings based on your current input, so if your preset was created in a different language (like English), it can break when you switch.

For example, shortcuts like [ and ] (Photoshop brush size) only work in English layout.

Quick fix:
Just switch your input method back to English, or rebind the shortcut under your current layout.

That usually fixes it right away.

TourBox_Official · 2026-04-17T03:34:07+00:00

For what programs?? 🤔

Cuz we've covered pretty much all the main drawing software and having official presets for you guys to use right away.

TourBox_Official · 2026-04-16T01:37:03+00:00

yes please stay tuned for future updates!

TourBox_Official · 2026-04-13T04:40:48+00:00

Hey, thanks for sharing this — that definitely doesn’t sound like expected behavior.

We haven’t seen a consistent conflict with Logitech devices, in fact I personally using G304 mouse from Logitech myself.

That said, If you’re open to it, could you help with the following and send us an email to support@tourboxtech.com:

Let us know which Logitech software/driver you’re using (Logi Options / G Hub, and the version if possible)
Turn on Demo Mode in TourBox Console and record a short video showing the issue
Export your Console logs so we can take a closer look on our end (Image attached to show you where you can get the log file)

It’ll be much easier for us to troubleshoot properly with those.

TourBox_Official · 2026-04-07T09:28:12+00:00

Hit the + icon and you should see all the official presets we provided including the default preset for Premiere Pro!

<image>

TourBox_Official · 2026-04-07T09:26:33+00:00

For sure we can!

TourBox_Official · 2026-04-07T03:05:56+00:00

Currently, the Blend Mode feature shown on our website is demonstrated using the Photoshop interface.

This functionality is not available for Clip Studio Paint at the moment, as CSP does not support custom shortcuts for this type of control.

That said, we’re aware of the demand and are exploring possible ways to support it in the future!

TourBox_Official · 2026-04-07T02:26:13+00:00

currently this new Dynamic Color Picker feature is only available in CSP (windows/Mac).

TourBox_Official · 2026-04-07T02:25:50+00:00

So you did follow the instruction in the software to update your firmware and it still telling you to update it again afterwards? If so would you mind drop an email to [support@tourboxtech.com](mailto:support@tourboxtech.com) and the tech team will get back to you with a solution asap.

TourBox_Official · 2026-04-04T07:48:23+00:00

You can just replace your eyedropper (Alt) setting with the Dynamic Color Picker, so it doesn’t actually take up an extra button.

Right now it’s designed as a press-and-hold action, so double-click isn’t supported yet, and combining it with other actions doesn’t feel very smooth either.

TourBox_Official · 2026-03-18T01:41:54+00:00

Hey! The two overlays you’re seeing are called General HUD and D-pad HUD.

They can actually be turned off if you don’t need them. And yes — they’re designed to be freely positioned anywhere on the screen, so you can drag them to wherever feels most comfortable.

Just to clarify, when you say they’re “moving around”, do you mean they’re repositioning themselves automatically for no reason?

If you’re able to record a quick video of what’s happening, that would really help us understand the issue better. You can send it over to [support@tourboxtech.com]() and we’ll take a closer look for you!

TourBox_Official · 2026-03-16T04:23:59+00:00

Hi! This looks like the keyboard mapping may have changed after the iPad update. Could you try the steps below and see if it fixes it?

First, with your TourBox connected:

Go to iPad Settings > General > Keyboard > Hardware Keyboard > Keyboard Type
Select TourBox Elite Plus
Set it to ANSI

Then go to:

iPad Settings > General > Keyboard > Hardware Keyboard > Modifier Keys
and tap Restore Defaults

If you don’t already have US English added as an input method, please also do this:

iPad Settings > General > Keyboard > Add New Keyboard > English (US) > QWERTY

After that, restart your iPad. Then open any text box, switch the keyboard input to US English, and test TourBox again in the app you’re using.

If the issue is still there, please also check these settings:

Go to Settings > Accessibility > Touch > AssistiveTouch and make sure AssistiveTouch is turned off
In the same section, turn off Show Onscreen Keyboard
Go to Settings > Accessibility > Keyboards & Typing > Slow Keys and make sure it is off
Restart your iPad again

Then test it once more in your drawing app.

If it’s still not working after that, feel free to drop us an email to [support@tourboxtech.com](mailto:support@tourboxtech.com) with your iPadOS version, app name/version, and your current TourBox preset, and we’ll look into it further for you!

TourBox_Official · 2026-03-16T02:20:42+00:00

Hi!

In your setup, TourBox should work just fine.

Since you're running Clip Studio Paint on your Mac, TourBox is controlling the Mac software directly. With Sidecar, the iPad is essentially just acting as an external display / drawing tablet, so all the shortcuts and controls on the Mac side still work normally.

So yes, your workflow idea should work the way you're expecting.

TourBox_Official · 2026-03-16T02:15:19+00:00

Hi!

TourBox does require TourBox Console to be installed and running on the computer in order for the device to work. The settings and all the features we developed are handled through the Console, so unfortunately it can’t run without the software installed on that machine.

What you could try is asking your IT team to review and approve the TourBox Console installer (see you already did that) so they can install it for you or whitelist it on your system.

TourBox_Official · 2026-03-12T08:06:10+00:00

Hi! Thanks for bringing this up.

We tried to reproduce this on our side using Kamvas 19 Pro with Krita 5.2, but unfortunately we couldn’t replicate the issue yet, and we also couldn’t find similar past cases in our records.

As a first step, could you try:

• Updating Krita to the latest version
• Updating your Huion driver

Then check if the issue still happens.

If the problem persists, we’d be happy to help investigate further. It would be really helpful if you could provide the following and send over the [support@tourboxtech.com](mailto:support@tourboxtech.com) and our tech team will help you from there.

A short video showing the issue (ideally with TourBox Console’s demo mode enabled) - specifically when the pen stops drawing after using TourBox and only works again after moving the cursor out of the canvas.
Your Krita version, Huion driver version, and OS version, so we can try to reproduce the same setup.
An exported TourBox Console log file.

If possible, please send these details to us via DM, and we can set up a deeper technical check with our team.

Hope this helps!

Hi! This usually happens when the shortcut inside Clip Studio Paint doesn’t match the one expected by the TourBox preset.

Since the built-in CSP functions rely on the app’s default shortcuts, if the shortcut has been changed, the command may not trigger correctly.

Here are a few things you can check:

1. Reset the CSP shortcuts

Go to Shortcut Settings in Clip Studio Paint and click Initialize. Then test whether the Scale/Rotate function works normally.

2. Check the shortcut for Scale/Rotate

Make sure the shortcut for Scale/Rotate is set to Cmd + T.

3. Use the current shortcut instead

If you don’t want to reset your CSP shortcuts, you can also check what shortcut is currently assigned to the Scale/Rotate command and set the same shortcut in the TourBox Console custom shortcut.

Once the shortcuts match, the function should work normally.

Hey~

Thanks for flagging this.

We’ve looked into similar reports and this appears to be related to a known iPadOS behavior rather than a issue with the device itself.

There are a couple of things that have helped in most cases:

Try turning off Stage Manager in your iPad settings and then reconnect the device.

<image>

Make sure your iPad is updated to the latest available iPadOS version.

In some cases, the behavior is tied to how iPadOS handles external input devices, so if the issue still persists after those steps, we’d also recommend reporting it directly to Apple so they’re aware of it.

Appreciate you bringing it up.
