Thank you for your reply, Chris.
This sounds like Mumble being brought out of being minimized and then minimizing
again, as if there were either no or two mouse clicks; i.e. this sounds like a
mouse button switch that's starting to go bad. I've had this happen to me, it
leads to thinking of all kinds of things being broken that aren't.
I have right clicked on the mumble icon and hit "Show"—which should only
ever allow one mouse click because it disappears—and still experience
this issue even with that. This can also happen when running 'mumble' in
a terminal with mumble already open and minimized to tray, or opening a
desktop file.
I've also run xev and clicked the window 100 times, saving the log to a
file[1]. This log contains no more and no less than exactly 100 mouse
button down entries and 100 mouse button up entries.
My mouse is also very new, I got it under 2 months ago, a SteelSeries
Rival 3.
So my first suggestion is to try changing mice to see if it's a mouse button
problem,
I have briefly switched mice to my old one, and I have the same issue at
the same reproduction rate.
and the second is to try adjust the mouse button timing in KDE settings
(especially if you have done so recently).
I cannot find these settings in KDE 5, but as I can reproduce without
using the mouse at all via a terminal or desktop file, I do not believe
this will help.
At first glance I suspect this isn't a Mumble bug, or at least that if it does
relate to Mumble directly that it doesn't happen on all desktop environments. I
regularly use the "Hide in tray when minimized" feature but not on KDE.
I agree, it does not seem to happen on all desktop environments.
I have a Sid VM where I think I'll try adding KDE Plasma to for testing.
I can try in a VM as well. I'll also give it a go in some other DEs and WMs.
I hope my testing is satisfactory, let me know if I can do anything else.
