Description Andrew Kelley 2024-12-20 01:04:05 UTC
SUMMARY

When you type, the mouse cursor disappears. When you move the cursor, it is supposed to come back. It fails to do this if a window has focus other than the one the mouse cursor is on top of.

STEPS TO REPRODUCE and OBSERVED RESULT
1. Open two Konsole windows side by side, A and B (any application will work)
2. Place the mouse cursor over the center of Window A
3. Alt+Tab to Window B
4. Enter text into Window B
5. Observe the mouse cursor disappear
6. Move the mouse cursor, observing it to be incorrectly invisible until it exits Window A's region

EXPECTED RESULT

When the mouse is moved, the cursor should reappear, even if a different window has focus.

I can't reproduce that issue myself on git master.

I can reproduce this on Fedora KDE 41, uploaded an attachment as an example - interestingly, the shake cursor effect causes it to temporarily appear, then disappear again until it's moved out from its current window.

I have a similar issue.
While watching a (seemingly only) YouTube fullscreen video, press and hold Alt-Tab the mouse only appears on the Task switcher.
It disappears when moved out and when shaking it will go visible only to disappear again, just like in the video.

I could not replicate the issue when switching windows.
