-- Information about the crash:
Since plasma 6.3, plugging in a displayport monitor (my primary monitor) causes plasma to crash. This is a similar issue to what happened in 6 (and possibly 6.1?) and was fixed in 6.2.

In addition, plasma jacks the brightness of the monitor to 100%. At least, I assume plasma does it, as plasma does offer brightness controls. I can use plasma to turn the brightness back down.


This often happens during waking my PC from sleep, as my monitor has a firmware bug causing it to appear unplugged to the PC when the monitor is powered off. (It's physically plugged in all the time.) I can avoid the firmware bug by turning off Freesync VRR on the monitor settings.

Sometimes when waking from sleep, my main monitor doesn't get a signal, continuing to act as if the cable was unplugged despite being plugged in and the PC awake. This never happened before the plasma 6.3 upgrade, but I also got a new kernel version during that upgrade, so this could be a kernel bug?

The reporter is unsure if this crash is reproducible.
