Description bastimeyer123 2022-05-18 16:17:28 UTC

Initial report: BUG 453943

SUMMARY
After the recent QML rewrite of the desktopgrid effect, the next click after moving windows between desktops will now get swallowed, which means in order to go back to one of the desktops after moving a window, you need to click twice.

Clicking while the opening/closing animation is playing or while windows are still animated also doesn't work as expected and the click sometimes will get ignored. This is especially frustrating when the animations are slow / their durations too long.

See https://youtu.be/A0ydBC6tvUQ


STEPS TO REPRODUCE
1. set up a grid
2. open some windows
3. move windows between desktops on the grid
4. try to left-click on a free space to return to one of the desktops

Are you on X11? And if so, can you not reproduce the issue on Wayland?

If that's the case, this is probably the same as Bug 451150 and Bug 451450, which all seem to have the same root cause.

Comment 2 bastimeyer123 2022-05-19 21:15:47 UTC

Nope, seems to be only applicable to X11.
