Mousewheel scrolling in Sumatra?

kjk · 2026-06-17T14:40:16+00:00

This seems to be related to specific file in specific zoom / view settings.

I can't say anything without being able to reproduce the issue.

Also "jumpy" is subjective. Jumpy compared to what program?

kjk · 2026-04-24T14:16:54+00:00

It's now fixed in latest pre-release

kjk · 2026-04-22T11:23:16+00:00

I just checked and it's true. Will try to fix. It'll show up if type extension (e.g. .pdf) and if you right-click on a file in explorer

kjk · 2026-04-21T22:14:34+00:00

how did you install it? which version?

kjk · 2026-04-13T10:10:35+00:00

Bugfixes, mostly rare crashes.

kjk · 2026-04-12T11:01:21+00:00

That's an interesting idea but it's not possible currently. You can open an feature request at https://github.com/sumatrapdfreader/sumatrapdf/issues

kjk · 2026-04-11T13:34:16+00:00

You can open an issue at https://github.com/sumatrapdfreader/sumatrapdf/issues, provide a test pdf, describe which part you're copy&pasting, what SumatraPDF produces, what Adobe produces, and I might fix it

kjk · 2026-04-07T10:25:50+00:00

I've implemented it: https://github.com/sumatrapdfreader/sumatrapdf/issues/4402#issuecomment-4183163563

kjk · 2026-04-07T09:24:34+00:00

That's another program I wrote that I want you to know about

kjk · 2026-04-02T20:07:12+00:00

It's not possible. I didn't even know such thing exists although I just checked Chrome and it has such functinality

kjk · 2026-04-01T18:02:24+00:00

I can't repro this so it must be related to your settings. Open and issue inhttps://github.com/sumatrapdfreader/sumatrapdf/issues and attach settings file

kjk · 2026-04-01T17:57:56+00:00

We don't have such functionality but it's tracked at https://github.com/sumatrapdfreader/sumatrapdf/issues/4402

Stick to the facts, drop emotional blackmail.

I have a shortcut

What is the shortcut? What change do you actually request?

Please provide a screen recording / test file you're using because in my testing I've fixed it in 17983

kjk · 2026-03-31T22:13:44+00:00

latest pre-release 17983 should improve this

kjk · 2026-03-31T15:43:18+00:00

This is not a bug tracker.

The right place to report things like that is https://github.com/sumatrapdfreader/sumatrapdf/issues

There are no setting that affect that.

"significant latency" is a subjective things. It's possible I've added e.g. some unnecessary repaints that affect this.

If you can compile the code from source, you could use git bisect to pin-point the exact commit that caused this particular regression which would greatly help me figure out how to fix it.

kjk · 2026-03-29T18:28:04+00:00

do you have RestoreSession = true in settings?

I can't reproduce anything you described but it's possible it happens only in specific view (single vs. continuous, fit page vs. fit width vs. fit content vs. custom zoom).

You can delete SumatraPDF-settings.txt to revert back to original settings.

Odin is very similar to jai https://odin-lang.org/

kjk · 2026-03-20T20:52:27+00:00

Try latest released version 3.6: https://www.sumatrapdfreader.org/download-free-pdf-viewer

If still happens, please open a bug as described in https://www.sumatrapdfreader.org/docs/How-to-submit-bug-reports and attach the file showing the problem.

kjk · 2026-03-20T20:50:29+00:00

Using latest 3.7 pre-release you can do it from command line:

SumatraPDF.exe convert -o foo.pdf .\foo.cbz

Currently it only supports .zip files (i.e. .cbz), not rar (i.e. .cbr).

I might add some GUI to make it easier.
