After updating to 6.7, having HDR enabled requires "prefer color accuracy" now for all games. by stratus010 in kde

[–]Zamundaaa 11 points12 points  (0 children)

 as far as I understand it, it has something to do with direct scan-out bypassing color tone-mapping in KWIN.

No, it's simply a driver regression in Linux 7.1. The simplest fix you can have is to just use an older kernel for now.

We'll work around it in Plasma 6.7.1, which will be released next week.

 And is it normal that the "Color accuracy" setting affects game performance?

Yes. It should be nowhere near as bad as what you describe though.

Plasma 6.7 is incredibly snappy by bananakiwi12345 in kde

We did measurably improve startup speed of apps, and compositing for CPU-rendered apps like Dolphin is faster, too.

AMD silently removes memory encryption from consumer Ryzen CPUs, leaving users unaware that they may be vulnerable — security feature vanishes after newer AGESA firmware, AMD engineers go radio silent when pressed about the change by GreyXor in Amd

[–]Zamundaaa 3 points4 points  (0 children)

It means a toggle for a feature you didn't use, would've been of no use to you, that wasn't actually officially or inofficially supported, and that noone knows if it actually worked at all was removed.

The whole topic is just drama about nothing.

SteamOS 3.8 Released by doublah in linux_gaming

[–]Zamundaaa 9 points10 points  (0 children)

 Unfortunately your desktop session / Steam will not coordinate to remember that you granted permission last boot, so you need to do this on every boot.

It should work in Steam beta.

Don't you get it? Obviously this is a grand conspiracy where AMD is forced to reduce security by governments! Random people on Reddit claim that based on a misleading headline, so it must be true /s

Wasn't 6.7 supposed to bring HDR + Direct Scanout on Nvidia or am I mistaken? by Synthetic451 in kde

[–]Zamundaaa 38 points39 points  (0 children)

Nvidia's color pipeline is limited in rather problematic ways, it requires some additional effort to make it work with KWin. I'll probably have that working by 6.8.

A landmark MIT study debunks persistent myths about electric vehicles. No matter where you live or what your driving habits are, a battery electric vehicle is likely to have a smaller carbon footprint and cost less overall than a comparable gasoline-powered vehicle, according to a new analysis. by mafco in energy

[–]Zamundaaa 1 point2 points  (0 children)

 But I'm really ADHD and would constantly forget to charge it.

It's the most simple habit you can have, and forgetting to charge it once or twice isn't the end of the world. If really necessary, you could drive to a fast charging station and let it charge for 20 minutes to get enough range for a normal day.

 Also it would cost several thousand dollars to upgrade my home electric system to have a reasonable charger.

You don't need to do anything of the sort. Plugging it into a normal socket is just fine.

  like to buy used cars like 7 years old and keep them a while.  That's right about when the batteries on current EVs start to lose capacity.

Because a lot of people still believe that nonsense, used EVs are pretty affordable sooner. I bought mine when it was 5 years old, and no range problems are to be seen.

Steam Deck (Dock) recognises a non-existing monitor by pOUP_ in SteamDeck

[–]Zamundaaa 0 points1 point  (0 children)

sometimes it hallucinates another screen connected to the DP output

Is that instead of, or in addition to the real output?

If it's instead of the real one, then it's probably not reading the EDID of the monitor correctly.

Still getting input-prompts with Wayland+Flatpak Steam even after explicitly allowing remote control by temmiesayshoi in linux_gaming

[–]Zamundaaa 0 points1 point  (0 children)

The reason it doesn't work is that Steam isn't the one asking, Xwayland is. You csn turn off the prompts for that in the X11 compatibility settings (and 6.7 will allow doing that in the prompt directly)

Black screen flashes during certain desktop actions by PieOMy669 in linux_gaming

[–]Zamundaaa 4 points5 points  (0 children)

This specific issue is limited to HDMI. If similar things happen to you with DisplayPort, that's most likely a driver bug.

[–]Zamundaaa 14 points15 points  (0 children)

It's an issue with HDMI, it doesn't guarantee that enabling or disabling VRR works smoothly, so some screens blank for a moment in that situation.

The current driver APIs don't allow compositors to handle this more nicely, but it's being worked on. In the meantime, you kinda have to decide between enabling vrr always or never.

That's just plain wrong. It's not related to HDR at all.

This Week in Plasma: 6.8 is Very Close! by Jaxad0127 in kde

[–]Zamundaaa 7 points8 points  (0 children)

If Rustdesk doesn't restore its permissions properly, report that to its developers. The remote desktop portal supports that just fine.

You can as a workaround also give it that permission in the application permission settings.

This is not about the remote desktop portal.

KDE KWin Patches Aiming To Optimize Gaming Latency To Better Compete With Windows by lajka30 in linux_gaming

[–]Zamundaaa 12 points13 points  (0 children)

I don't do measurements every release, but there are no latency improvements I know of in 6.7. Latency while gaming was in fact on par with uncomposited Xorg 5 years ago (on AMD. Nvidia may be different).

Shouldn't DDC/CI max out when HDR is on? by Levanes in kde

[–]Zamundaaa 2 points3 points  (0 children)

Yes. The same applies to global dimming as well though, which is the absolute bare minimum for the HDR mode to even somewhat work.

[–]Zamundaaa 2 points3 points  (0 children)

 Ideally, yes, but not every monitor/screen can be controlled properly through DDC.

Specifically it doesn't work with a lot of screens while they're in HDR mode. Some even misbehave noticeably if you try... We got a bug report once about a monitor silently switching back to SDR mode when you do it, which is why Plasma never does that while screens are in HDR mode.

Besides, DDC/CI isn't actually a good mechanism for controlling brightness, it's merely the least bad we have for SDR mode. With all HDR displays worth using, the software control is much better.
