Bug ID: 504593
Summary: KWin Wayland DRM - Thread hangs when middle mouse
button (scroll wheel) pressed.
Classification: Plasma
Product: kwin
Version First 6.3.5
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: wayland-generic
Assignee: kwin-bugs-n...@kde.org
Reporter: isaac17pe...@gmail.com
Target Milestone: ---
SUMMARY
STEPS TO REPRODUCE
1. Open a window
2. Press middle click on mouse
3. Move mouse up/down
OBSERVED RESULT
Entire OS hangs. I've found turning one monitor off and on again seems to
somewhat resolve it, or it may just be a time thing.
EXPECTED RESULT
Should scroll the window, not hang the whole system.

on my system.

thread was hanging temporarily!
