I built KWin with that patch but didn't notice any extra log entries, then
realized I didn't build debug build oops
Now with debug build I see same
> "" 3469 wants an idle notification with too big timeout 4294967295
where 3469 is `org_kde_powerdevil`
But I disagree that this is Powerdevil's bug. KWin should either respect this
and notify after ~50days or ignore it and potentially let application know this
in some way.
Powerdevil doing some stupid shit is just another bug - of course should be
fixed but that doesn't mean KWin shouldn't be fixed aswell because ANY
application can send garbage to it.

Another interesting thing I found that if you restart KWin then it doesn't
happen anymore, maybe because Powerdevil stops working?
This is what Powerdevil says after KWin restart
> The Wayland connection broke. Did the Wayland compositor die?
> qt.qpa.wayland: Attempting wayland reconnect
> Failed to write to the pipe: Bad file descriptor.
> qt.qpa.wayland: Creating a fake screen in order for Qt not to crash
But now if I restart Powerdevil (/usr/lib/org_kde_powerdevil --replace) then it
starts happening again.
Also btw I see these messages in Powerdevil aswell
