--- Comment #50 from Andrew T <[email protected]> ---
I was consistently hitting this issue under Fedora 43 and managed to get a
consistent reproduction, confirmed with a couple of people in the Fedora forums
(https://discussion.fedoraproject.org/t/crashing-konsole-since-upgrade-to-f43/177471/15):

* Open Konsole and run the bash snippet `while true; do sleep 0.02; echo 'a
line of text that covers a about half a row, give or take'; done`
* Move the Konsole to another desktop or change virtual desktop away from it
* Wait a few seconds for the crash notification

Variants without the sleep, values of 0.01 or 0.1 and higher don't seem to
exhibit the crash, 0.05 takes a bit longer to crash. I originally consistently
noticed this problem running scripts over SSH and after local attempts to
replicate, tried an interleaved sleep to replicate the slightly slower stuttery
output. 

I have a T480 laptop and what is happening is obviously timing sensitive, so
different machines may not be as consistent. A couple of people in the FC
forums gave it a go and did report that it was happening for them, every time.

> Potential fix from openSUSE ?

I pulled down the current Fedora SRPM (qt6-qtbase-6.10.1-2.fc43.src.rpm ) and
applied this patch from the SuSE ticket, after a rebuild, can confirm no more
crashing.

Additionally, for a quick, no-rebuild workaround, `konsole --platform xcb` to
avoid using the Wayland backend with the problem stops crashing for me.
