Description Sontol Bonggol 2018-05-26 04:06:40 UTC
As described in the KDE forum (https://forum.kde.org/viewtopic.php?t=141296):
I've recently upgraded to Plasma 5.10.4 and I'm having an incredibly annoying issue. Occasionally, ALT-TAB is ignored the first 1, 2 up to 5 or so times, and then it finally works. This is unacceptable because when I'm programming / debugging / testing I have to switch windows and do a lot of different things and I don't have time to wait for visual confirmation that my keyboard command was acknowledged. I just send keystrokes to my hands and expect the computer to work, but end up typing into the wrong window because of this.

Make sure ungrab keyboard request is processed before emitting shortcut

In some rare cases, the ungrab keyboard request is processed later than
the action of the key shortcut. This can make the application that try
to grab the keyboard (e.g. in kwin) fail to do so. The solution is to
use ungrab_keyboard_checked() and xcb_request_check() before emitting
the shortcut signal.
