Swapping to Wayland on Plasma has brought a few issues for me.
Namely, popups don’t seem to know the bounds of the screen.
This has resulted in things like notifications showing up offset to the actual corner of my screen, or latte-dock just hanging out in the bottom-center.
If this is a scaling issue, it would also seem to be the reason behind blur effects only affecting the top left of windows. Interestingly, the amount notifications are offset from the real edge of my screen is quite close to the ratio that the blur effect is shrunk by.
I do not know for certain if this is related, but nested dropdowns also don’t match my mouse cursor’s position correctly to the item in the dropdown list.
I am not using global scale to scale up my screen, nor a non-native resolution set. Although an NVIDIA GPU is in the computer, the Intel iGPU is the only one used.
Based on the advice from this KDE bug #461856, I added QT_WAYLAND_DISABLE_FIXED_POSITIONS=1
to my environment but this had no change on any of the three issues. This does not occur on X11, but I am moving to Wayland for fractional scaling in the future.
Any help would be appreciated.
