Hello!

Sorry I’m posting this here since I don’t think is specifically related to KDE but since I use KDE and is where I found it the first time I figured some of you might be able to help!

I found a bug that seems too affect many apps and I’m not sure where to report it. Let me explain the issue and hope some of you know where to report that!

So the other day I reported the bug on Krita that you can see on the video but later on saw that this seems to happen to many apps in Linux! So I entered a bit into a rabbit hole and tried many things. This same thing happens to GIMP, KolourPaint, etc. and it seems to be independent on the distro or the Desktop environment!

I’ve checked on Fedora, CachyOS and SteamOS (with Wayland and with X11) and also tried KDE and Gnome. All of them had this issue and then tried Krita on a macbook and didn’t seem to have the issue (correction: seems it's speed dependent. If you move the mouse too fast it doesn't do it else it does). And some of them where different computers too.

Does any of you know where this kind of things should be reported? This seems to be very fundamental and I have no idea where this should be reported. Any iedeas?

Edit: Since there seems to be some confusion here's the bug report:

SUMMARY Drawing a line with the brush creates a zig-zag pattern based on the zoom level

STEPS TO REPRODUCE

1. Select the Freehand Brush Tool (B)
2. Set size to 1 px (happens in all sizes but 1 px is very clear)
3. Zoom out with the wheel
4. Draw a diagonal line
5. Zoom in with the mouse wheel
6. Draw a diagonal line

OBSERVED RESULT The line drawn when zooming out has a zig-zag pattern to it (like a stair) while the zoom in line has less or none (depending on the zoom level).

EXPECTED RESULT Both lines should be a smooth diagonals instead of a zig-zag pattern.

SOFTWARE/OS VERSIONS Operating System: Fedora Linux 43 KDE Plasma Version: 6.6.3 KDE Frameworks Version: 6.24.0 Qt Version: 6.10.2 Kernel Version: 6.19.10-200.fc43.x86_64 (64-bit) Graphics Platform: Wayland

Hardare used to draw: Logitech Gaming Mouse G502 I've also tested with the touchpad and my brother's computer with different hardware and mouse. This also happens there and even on the Steam Deck so it's definetely not a hardware issue.

Link to the bug report I first did: https://bugs.kde.org/show_bug.cgi?id=518636

Does anyone know where this should be reported?
