SUMMARY
When switching from Desktop 2, to Desktop 1, Konsole Crashes, seemingly at random, but most often when the shell in the konsole is inside a distrobox

STEPS TO REPRODUCE
1. Open Konsole on Desktop 2
2. run distrobox enter
3. run something that causes terminal scroll (like compiling something)
4. Press <ctrl-F1> to switch from Desktop 2, to Desktop 1

OBSERVED RESULT
Konsole crashes, and generates a coredump in coredumpctl

EXPECTED RESULT
Konsole doesn't crash
