Bug 444385

Actually does not seem to be related to the uptime of the system. I can reliably reproduce with Firefox running a Twitch.tv stream.
I can confirm the problem with these two applications:
- Wire (Electron application)
- Gajim (XMPP Client)

Here is a video of the issue happening:
https://youtu.be/SGVwq4sj33Q

The system state gets progressively worse over a few seconds.
I right clicked the Wire Icon (tooltip electron11) two times with a few seconds in between. I am trying to minimize the Firefox window.
The twitch stream stopping is part of symptoms.

If there is additional info needed or if I should try something specific, just ask!

Also happended to me without Firefox running, it's just that somehow Firefox running a Twitch streams leads to reliable reproduction of this issue.

Bug seems to be caused by plasma-workspace repo.
v5.22.5: Everything works as expected
v5.22.90: There is no random inputs happening, but the menu also doesn't open
v5.23.0: The original described behaviour happens.

I will try to bisect further.

I identified that the following commit introduced this behaviour:
https://invent.kde.org/plasma/plasma-workspace/-/commit/6545d5584d01c452121efcb12305d7f1fde84b4d

I did some more testing and can conclude that only applications using GTK3 are causing this behaviour. Qt applications work fine even with the bug introducing commit applied.

Errant Mouse After Tray Click

OH MY GOD! This is BY FAR the MOST egregious bug I've encountered with KDE... and that's so far beyond the "desktop icon scrambling" bug or the wayland issues, and it MUST get the highest priority nate/david/feck/whomever!

I just now encountered this issue, and I had just upgraded my system last night, since my previous upgrade was on the 13th.

I was composing an email reply in my browser and went to open up skype in the system tray and EVERYTHING went haywire. I had no control over "context menu" actions that were being taken.

The browser brought up developer-tools. I figured it may be related to the compositor since dropping x-render happened, but on the other hand I don't see how since compositing and actions shouldn't be related.
But still, I went to bring up settings and that too went haywire and the entire task tray started filling up.

I had to switch to another tty since I couldn't stop any of it. I killed plasmashell, and I think that did it, but the damage was done, as shown in the attached image.
I had already started removing a lot of those extra "settings" in the bar, but doesn't look like I made a dent, so I'm going to look for whatever file is in charge of the layout and manually clean it up there since that should be faster.

In the journal, when it all went wrong (start at the bottom):

In short, you've got me terrified to touch the system tray.

75 instances? Yeah, no way would I have enjoyed manually clicking/removing them one-by-one.

If you want it fixed please don't make it harder to find the useful information that faerbit has gathered.

? I saw no acknowledgement of the issue, including whether or not the suspected commit relates to the bug, and I was lending my experience with the issue AND including log output, whether it affirms the commit or may point elsewhere.

I had no idea my submission would be a hindrance.
Carry-on and ignore if you already know what's up.

Of course: KWindowSystem::lastInputSerial does nothing on x11 and as the connection persists that lambda will keep firing.

A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/1149

Faerbit as you were already compiling things, could you test that patch. 
I've had to guess at the causes from the clues above, so I can't be 100% sure it fixes your problem.

I tested the patch, and it stops the synthesised input events, so no more freaky mouse clicks all over the place. But apparently it stops all of these, since the right-click menu doesn't open, which it does with v5.22.5.

Disconnect watcher for xdgActivationTokenArrived

XdgActivationTokens are loaded async. To acheive a job like pattern we
were comparing serials in our slot when one was created.

On wayland this isn't ideal because we're slowly building up an
increasibly long list of lambdas being run, but they'll all no-op.

On X11 because lastInputSerial is always 0 we run the slot multiple
times for every system tray item each time an item is clicked or an
application is launched.

For xembedsniproxy this is especially problematic problematic as we will
trigger synthesised input events in our slot.

I am confused. Will the breakage of the right-click menu not be addressed?

Thank you for the fix, and for reopening this. If you need further testing I will gladly do it.

This happens with Java applications too. When I use Jdownloader2, if I right click on it's systray icon, Plasma goes CRAZY - I can't click anywhere, small black boxes are opening around the panel, archives are created here and there, favorites are being added to the side panel in Dolphin, etc. - it's a disaster. Only a restart fixes that. 
I observe one more problem related to systemtray - if I have Viber loaded, after certain amount of time there are misclicks - for example, if I click on qBittorrent's icon, Viber context menu opens along with qBittorrent's menu. If I quit Viber, this fixes the problem for a while.

Every release I hope this will be fixed! KDE has only two significant stability issues for me, and this is one of them. I have to restart plasmashell at least twice a day.

Maybe I didn't test correctly before. However it is completely fixed in 5.23.3 for me; right-click opens the menu as before.

Sadly, with Plasma 5.24 the problem is here again .

>Sadly, with Plasma 5.24 the problem is here again .

The same bug with the same cause is not. 

Your comment in #19 also didn't quite match the original report. Please reopen a new bug so we don't confuse it with old information and provide some more details as to what is broken.

My fault, I'm sorry.

I was able to trigger the "click storm" event with 5.24, by holding down left mouse button on a tray icon. Click-and-hold.

The original issue was about right-clicking, so it does indeed sounds like a different problem.
