-- Information about the crash:
Device: 2-in-1 laptop (Framework 12), which has a touch screen and a rotation sensor.

KWin crashes on wake from sleep when in tablet mode. 

I can reliably trigger the crash by following these steps:
1- Fresh boot / reboot (see notes below)
2- switch to tablet mode. I do this by folding the laptop open beyond 180 degrees.
3- enter sleep mode (either by waiting or by tapping the sleep button in the Application Launcher)
4- wait a few seconds
5- wake using touch
6- sleep again and wait a few seconds
7- wake using touch (ideally a double tap)

You might need to repeat the sleep/wake sequence (steps 6 and 7) a few times. I tested the sequence above many times, and I was always able to trigger the crash within a few sleeps at most. I can only trigger it in tablet mode so far.

The crash often results in disabling power management and brightness control (I cannot access them in the control panel, and I cannot use keyboard buttons to adjust the brightness). This is notable because I cannot trigger the crash again until they're re-enabled (by rebooting). Sometimes, the crash doesn't disable power management and brightness control, and in those cases I can re-trigger the crash without rebooting.

Finally, I suspect this is related to https://bugs.kde.org/show_bug.cgi?id=514082.

Happy to provide more info if needed. Thanks!

The reporter is unsure if this crash is reproducible.

Thank you for the bug report. Based on the backtrace this looks like a duplicate of bug 514082 so I'll merge this report in with the other one. This looks to be fixed in the upcoming Plasma 6.6 release. If this crash still happens in that release, please re-open 514082.
