breeze task switcher crash (sid)

[Edward Shornock <ed.shornock@gmail.com>]

Hi,

I haven't seen my problem reported on the list yet and haven't found any applicable bug reports.

Debian Sid
Plasma: 5.26.0
Frameworks: 5.98.0
Qt: 5.15.6
X11
Nvidia Legacy driver: 390.154-2
kernel: 6.0.0-2-amd64


kwin crashes when I press ALT+Tab with the Breeze task switcher enabled.

A few of the other options (brought with kwin-addons) also crash but breeze dark, for example, does not crash.

I don't believe I have any package mismatches. I don't know if installing additional packages would make the crashing stop, hence posting to this list before filing a bug report.
