Description Patrick Silva 2022-05-15 12:25:35 UTC

STEPS TO REPRODUCE
1. use Wayland session
2. open Screen Edges KCM
3. choose another action to the upper left corner - I chose 'Desktop Grid'
4. click on 'Apply' button and do NOT move the mouse pointer

OBSERVED RESULT
mouse pointer disappears after the last step. It reappears when I move my finger on the touchpad.

EXPECTED RESULT
mouse pointer should not disappear after changing settings
