Bug ID: 499992
Summary: UI crashes on alt tab in Kubuntu 24.10 running on a
Hyper-V VM
Classification: Plasma
Product: kwin
Version: 6.1.5
Platform: Kubuntu

Status: REPORTED
Severity: crash
Priority: NOR
Component: tabbox
Assignee: kwin-bugs-n...@kde.org
Reporter: anshul.si...@canonical.com

SUMMARY
The UI seems to crash whenever I try to switch tasks with alt tab. When I
alt-tab and use arrow keys the screen just crashes and goes black for around
4-5 seconds and then I get the switch. In the meantime I can’t see the switcher
either. I’m running Kubuntu 24.10 in a Hyper-V VM and I started facing this
issue since the 24.10 update, it used to work fine in 24.04.
STEPS TO REPRODUCE
alt-tab and use arrow keys to switch
OBSERVED RESULT
screen goes black and UI crashes(?)
EXPECTED RESULT
I should be able to see and navigate through windows on the task switcher
