Description rileyjones207 2025-10-05 01:43:19 UTC
SUMMARY


STEPS TO REPRODUCE
0. With mouse navigation / mouse keys enabled
1. Hold numpad 5
2. Move cursor using physical mouse

OBSERVED RESULT
After around 1 second, the drag or highlight action will end without you letting go of numpad 5.

EXPECTED RESULT
Mouse cursor would continue dragging or highlighting selection until numpad 5 is released.

WORKAROUND
Before moving the mouse, press any key on keyboard. This gives the expected result.

SUMMARY
When using mouse navigation / mouse keys along with a real mouse, any highlight or drag action started with numpad 5 will automatically end. This does not occur if you only move the cursor using the keyboard or if you press any key before you move the mouse.

Can reproduce.

Note: it doesnt happen if you move the cursor with numpad keys first.

Is this a KCM issue or KWin issue?
