konsole backtrace
SUMMARY
Maybe the connector of my non-MST display got loose, thus kwin switched to the
previously turned off display (first in a MST chain), upon discovering the
display again, it switched the configuration back and I find crash
notifications for kwrite and konsole.
In the journal I see:

order for Qt not to crash
and lots of firefox warnings:
Couldn't map window 0x7a02a7ff27a0 as subsurface because its parent is not
mapped.
then
