Bug#840141: kwin-x11: Short freeze when showing multiple tray notifications
Hi,
If there's a way to provide more info (even with minimal recompilation),
I'd be glad to. Fixing this freeze can't happen to soon.
Running kwin and plasmashell from the terminal I get the following
outputs when the freeze happens:
Currrent active notifications: QHash(("notification 211", "Network
managementBluetooth (A0:E4:53:AC:F7:07)"))
Guessing partOf as: 0
New Notification: "Xperia Z1 Compact Network (nap)" "Connection
'Xperia Z1 Compact Network (nap)' deactivated." -1 & Part of: 0

However, the QXcbConnection part seems unrelated, since it is not always
correlated with the notification and the freeze. I've also attached
.xsession-errors from the last minutes when this reproduce, but to me it
seems to not contain anything related.

Hola!
I believe this is rather and interaction between KWin and Plasmashell.
If I stopped the Plasmashell process, the freeze doesn't happen
anymore (those notifications are drawn at the top of the screen in
small windows). A further argument for this idea is that after the
freeze the screen goes one "frame" back, and that the music and cursor
are not affected.
I'll note that after restarting Plasmashell this doesn't happen as
reliably as before.
However, if you know a good way of triggering this kind of
notifications, it will be my pleasure to do it.
Thank you,
Alex

Package: kwin-x11 Version: 4:5.7.4-1 Severity: normal
The entire screens freeze for a couple of seconds (3-4, but
sometimes seemed close to 10) everytime notifications from the tray
are about to scroll down or disappear. This only affects drawing of
screen content, it doesn't affect sound or cursor motion.
If relevant, the particular tray notifications are about bluetooth
devices, I'll attach a screenshot with this. The particular order is
like this:
-two messages (M1 - connection deactivated, M2 - connection timed
out) appear one above the other -2-3 seconds pass -freeze -2 -freeze
ends -M1 disappears, M2 animates going down -messages reappear and
animate again, but without freezes.
I'll send a screenshot after the bug is created, and if possible a
recording.
As reported it seems that the issue is bluetooth specific, and it
might be caused by an underlying issue of the bluetooth kernel module
or hardware device. In my limited tests I couldn't reproduce this
behaviour in my laptop.
Would it be feasible for you to test this multiple bluetooth
notifications in a different desktop environment in order to rule out
a kernel/hardware issue?
Can you reproduce this triggering a different type of notifications?
Happy hacking,
