Bug ID: 450050
Summary: Desktop functionality degrades after a notification
can't be shown (DBus connection instability?)
Product: plasmashell
Version: 5.23.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: torokat...@gmail.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
SUMMARY
>From time to time, when Firefox tries to show a desktop notification about an
incoming email in an open GMail tab, it is unable to do so, and instead, gets
locked up for several seconds; then either crashes, or causes the whole desktop
to enter a strangely degraded state.
STEPS TO REPRODUCE
1. Have GMail open in a Firefox tab
2. Receive a desktop notification about an incoming email
3. Repeat sufficiently many times in different conditions - it does not occur
every time
I think GMail is most likely not relevant, and any "Notification API Tester"
application could potentially trigger this.
Maybe Firefox isn't important either
I just happen to always have this happen in these circumstances - and I noticed
the correlation because my phone also pops up the notification at the exact
same time these freezes happen.
OBSERVED RESULT
Firefox is unable to show the desktop notification, instead, becomes completely
unresponsive for several seconds, and sometimes crashes after a while. If it
doesn't, these effects (the degraded state) come into play:
- Notifications about any further incoming mail are not shown as the usual
notification popup, instead, as a fallback within Firefox (I suppose) - in
proper popup windows, with frames and taskbar entries, and with completely
different appearance than my system theme, and in random positions on the
screen, with a Firefox icon.
- System tray icons for applications (such as Discord, Steam, KTorrent) are no
longer responding to selecting any item of their context menus; nor does the
set of visible icons change anymore when I open or close applications that
normally have icons in the system tray.
- The Shut Down/Restart/Sleep options in the Application Launcher no longer do
anything.
- The volume up/down keys on my keyboard no longer do anything.
- The panel otherwise remains mostly operational: switching between windows
works, the list of windows is up to date, launching applications from the panel
works, and interacting with other widgets and non-application icons on the
system tray are also operational, such as those for volume adjustment or
network management.
EXPECTED RESULT
All notifications from all applications are shown normally, and no element of
the degraded state described above is ever realized.
SOFTWARE/OS VERSIONS
Linux: Fedora 35 KDE
KDE Plasma Version: 5.23.5
KDE Frameworks Version: 5.90.0
Qt Version: 5.15.2
ADDITIONAL INFORMATION
Not much at the moment, but I am happy to provide any logs or config files when
instructed on how to make or retrieve them.
I have a habit of running plasmashell from a terminal window, so that I can
quickly kill and restart it in case this happens again, and I used to see some
DBus-related error messages in the degraded state - also, the missing
interactivity between applications hints at maybe the server crashing, or
plasma's connection being dropped?
