           Summary: Plasma glitches and crashes after update to Linux
                    6.14.2

           Product: plasmashell

                OS: Linux

SUMMARY

After updating my kernel from 6.13.2 to 6.14.2 I started to experience multiple
glitches and hangs in Plasma.

STEPS TO REPRODUCE
1. Update Linux to 6.14.2.

OBSERVED RESULT
Multiple hangs and glitches: Right after boot my desktop is completely
unresponsive for ~30 seconds, clicking stuff in the taskbar doesn't do
anything. The Wi-Fi doesn't connect. Sometimes it crashes (I assume), because
the taskbar disappears and then after a few seconds appears again.
When shutting down there's a ~15 seconds hang with some errors on the screen
about watchdog (I guess some process is not responding?).

EXPECTED RESULT
Plasma works normally.

SOFTWARE/OS VERSIONS
OS: Arch Linux
KDE Plasma Version: 6.3.4
KDE Frameworks Version: 6.12.0
Qt Version: 6.9.0

ADDITIONAL INFORMATION

Rolling back to Linux 6.13.2 fixes all the issues. The glitches are persistent
and reproducible across reboots on 6.14.2.

I can provide more debug logs and test something if you tell me where to look /
what to do. The problem seems to be fully reproducible.
