file a bug against powerdevil (though it might be in some frameworks class,
don't know how the nasty brightness indicator is implemented)

The reason will be that the indicator is not override_redirect and does not
refuse focus, so it gets activated and the netwm spec requires fullscreen
windows to shift back to the normal layer when they loose the focus (desired
behavior because otherwise the active window would not get in sight). This
implicitly drops them below panels (and some other windows) as well.

[kwin] [Bug 356740] Kwin crash if I set brightness while in kodi

Ok, so it does not crash anymore when I set brightness while in Kodi, which is
good, but the behaviour is still weird:

Each time I increase or decrease brightness, the plasma taskbar is shown a
brief moment, so when increasing several time it feels as the screen is
flickering, as it shows kodi and plasma desktop several time each in a few
seconds.
I don’t have this problem when increasing or decreasing audio volume, I only
get the KDE volume indicator on top of Kodi (which does not indicate much
anymore as both bar colors are almost the same but I should open a bug ticket
on breeze for this I guess).
I would like the same for brightness, the brightness indicator at the center
only above kodi, no flickering with plasma desktop or taskbar.

That's bug #346118 - certainly not related to kwin and unlikely related to
changing the brightness in kodi.

There is a qt5/plasma update available, I’ll give more information after the
update is done and I try again.

(In reply to Côme Chilliet from comment #2)
> had to reboot as kwin was crashed and nothing worked anymore.

So it's no segfault? What makes you believe that kwin "crashed"?  (And not eg.
kodi while it grabs input? It has a feature to disable that so you can use
global shortcuts etc.)

Backtrace or it didn't happen :-P

(When kwin crashes it should restart and you should get a crash dialog - we
need the developer information - no idea how this should relate to brightness
changes in kodi, but smells like the epic qscreen bug)

First, I had the dialog in the same situation before.
And second, I also got the crash while having alt+tab before, in which case I
can see window got no decoration anymore, focus can’t change between windows
and keyboard is not responding anymore (maybe linked to the focus thing).
When the crash happens while in kodi, I can’t alt+tab anymore but kodi works
fine.
Maybe in this case it’s not kwin which is crashing, I don’t know, but when I
had the crash dialog before it always said «kwin».

I did before, but I tried a few times and I got no dialog. And each time I had
to reboot as kwin was crashed and nothing worked anymore.
I’ll try again tomorrow (getting late here).
