Bug ID: 401227
Summary: Global hotkey resets with each restart
Product: kwin
Version: 5.14.3
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: input

Target Milestone: ---
SUMMARY
KWin seems to steal focus when the key combination Alt+= is pressed, but I
can't figure out what it does exactly. This is a problem for me because I
typically use this hotkey in Emacs to do a specific task. However, since KWin
steals the focus every time Alt+= is pressed, I can't use it in Emacs.
STEPS TO REPRODUCE
Open xev and press Alt+=. The following is a commented output from my machine:
# Alt pressed:
KeyPress event, serial 40, synthetic NO, window 0x5800001,
root 0x1c9, subw 0x0, time 3737607, (61,104), root:(1461,133),
state 0x0, keycode 64 (keysym 0xffe9, Alt_L), same_screen YES,
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
# = pressed:
FocusOut event, serial 40, synthetic NO, window 0x5800001,
mode NotifyGrab, detail NotifyAncestor
FocusOut event, serial 40, synthetic NO, window 0x5800001,

XLookupString gives 0 bytes:
XFilterEvent returns: False
You can see things like FocusIn and FocusOut, which means that a KDE process is
invoked by the key combination. I believe this is related to KWin because when
I close KWin,
killall kwin_x11
the shortcut becomes available in Emacs and other applications (it's not
intercepted by KWin). If I then start KWin,
kwin_x11 &
the shortcut becomes again bound to a KWin and is not available by other
applications.
I went through all the global and standard shortcuts but nothing seems to be
bound to Alt+=. The only way I can fix this is by assigning Alt+= to some
action and then removing it which frees up the key combination. However, after
a restart Alt+= is again bound to some unknown action.
EXPECTED RESULT
When this shortcut is disabled, it should stay disabled even after KWin
restarts.
