Bug ID: 479492
Summary: plasmashell exits with large(ish) number of windows
Classification: Plasma
Product: plasmashell
Version: 5.27.9
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: wbs8o5...@mozmail.com

Target Milestone: 1.0

Output from strace plasmashell, exiting immediately after startup.
SUMMARY
If I open "too many" windows, plasmashell exits with the message
> The Wayland connection broke. Did the Wayland compositor die?
resulting in the panels and root window background disappearing, etc.
plasmashell does not appear to crash - there is no indication of a coredump -
it simple exits with status 1.
I'm not sure how many windows are "too many". I was roughly guessing about
100. xwininfo currently says the root window has 165 children, if that helps -
but I see what appear to be a lot of duplicates in its list.
When I discovered what was happening, I started running plasmashell from an
xterm so that (a) I could continue working, and (b) so that I could see its
output. Sometimes there are additional error messages before the one shown
above, but that is the only one that's consistent.
It seems that when I'm near the limit, plasmashell becomes increasing unstable
as more windows are opened. Beyond a certain point, it exits immediately after
it starts. If I then close some windows, I can restart plasmashell and it will
run again until I open more windows.
I'm attaching output from plasmashell running under strace. In its current
state, it exits immediately after starting it, with no other message than the
one shown above.
STEPS TO REPRODUCE
1. Start session, open applications (web browser, numerous xterms, gitk,
Ardour, okular, ...).
2. Continue opening windows, keeping an eye on the panel containing task
manager (for me this is at the bottom of the screen)...
3.
OBSERVED RESULT
With somewhere between 50 and 150 open windows, an additional window seems to
cause plasmashell to exit with zero or more error messages, always ending in
the on cited above.
EXPECTED RESULT
Session continues to operate normally; panels and their apps continue to
function, and I'm blissfully unaware of plasmashell. :-)

I have not installed proprietary nVidia drivers, and it appears I'm running
nouveau - I see it in lsmod's output. (I've previously played around with
switching between Intel and nVidia GPUs and didn't remember how I left it.)
