Description Harrison 2022-08-26 03:09:16 UTC 
SUMMARY

STEPS TO REPRODUCE
1. Enable alt+tab window switching
2. Press, and hold `<tab>`, then press `<alt>`
3. Observe a black screen

To exit, wiggle the mouse or press `<alt> + <tab>` (in that order and together) and observe that the plasma desktop session is restarted.

OBSERVED RESULT

Black screen and restarted plasma session

EXPECTED RESULT

Either,
1. Same behaviour as `<alt>+<tab>` (in that order and together, i.e. the order of button presses shouldn't matter)
2. Do nothing (i.e. the key combo should be ignored if the ordering is not precisely `<alt>` then `<tab>`)
