Description Dashon 2023-10-16 01:57:25 UTC

SUMMARY
In a wayland session, (Doesn't Happen on Xorg). If you have wobbly windows enabled and you move the window up and down enough times. The window will slowly resize itself.


STEPS TO REPRODUCE
1. Enable wobbly windows inside of system settings -> search for desktop effects -> search for wobbly windows.
2. In a wayland session, drag any resizable window by its titlebar up and down.

OBSERVED RESULT
Window slowly gets smaller and smaller.

EXPECTED RESULT
The window should stay the same size. The drag action should not trigger the resize action.

I can't seem to reproduce it on my laptop with a trackpad at 1080p, but it is super easy to trigger on my desktop at 1440p

Also I have the wobbly window slider on the highest setting.

After swtich back to x11. It seems it is now happening there as well. I think it may have something to do with the scaling factor between wayland and x11. Seems like all types of stuff got wonky after switching between the two.

I disabled wobbly windows and it is still happening. At this point I don't know what is going on. Some windows even get resized to the point that they are nonexistent and I have to kill them from system monitor.

I resolved the issue by nuking a bunch of files in .local.
