Pressing two keys on a standard US keyboard will DDoS the KDE completely to a
total freeze.
SUMMARY
Pressing two keys on a standard US keyboard will DDoS the KDE completely to a
total freeze. You will destroy unsaved documents and create errors in
harddrive/filesystem via the unavoidable hard power button reset (reuso+reisub
does not work). Total freeze.
STEPS TO REPRODUCE
1. Log in to KDE
2. For a better effect, play a video form your hdd, e.g. via mpv (not required,
but encouraged)
3. For a better effect, do not close Dolphin (not required, but encouraged)
4. Open a very important document in Kate to edit it, try to save it via
pressing "ctrl+s", but miss intentionally/by mistake Fn insted of ctrl, so d
number 5 below:
5. PRESS "Fn+s" (instead of ctrl+s).
OBSERVED RESULT
1. Unlimited number of spectacle screenshotter is launched
2. Infinte number of openining Specacle windows will DDoS the KDE and WILL
TOTALLY FREEZE THE SYSTEM
ADDITIOAL INFO:
1. Standard Shortcuts/Default KDE Shortcuts
2. Default Sepctacle shortcut removed, only PrintScr left
3. Nothing helped: Undocumented Fn+s is still DDoS-ing KDE
How many times it happend this to me befor I decided to report this graveyard
bug:
As far as I remember from 7 - 10.
EXPECTED RESULT
Remove undocumented shortcut: "Fn+s" and MAKE SURE that neither documented or
undocumented shortcuts will DDoS KDE.
This is NOT cool!
