Description Dmitry 2017-07-19 19:45:54 UTC

Application: plasmashell (5.10.3)

Qt Version: 5.7.1
Frameworks Version: 5.36.0
Operating System: Linux 4.10.0-28-generic x86_64
Distribution: Ubuntu 17.04

-- Information about the crash:
- What I was doing when the application crashed:
Disconnected two external displays from laptop

- Unusual behavior I noticed:
One of the panel (on the bottom of the screen) disappeared. Restored after plasma restart.

- Custom settings of the application:
Tho external displays connected to laptop. Two panels (one top, one bottom) on the first (left) display, one panel one the bottom of the second display.
Internal laptop display is disabled, when external ones are connected.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Comment 4 Nuno Costa 2020-12-23 21:00:02 UTC

I can replicate the issue I reported on bug 390766 with different hardware.
This time the segmentation error does not appear but taskbar on secondary screen does not show any apps.
My setup now only 1 external monitor and a laptop connected with HDMI.

External monitor is the main screen and have a “normal” taskbar.
Laptop screen have a vertical icon only taskbar.

If I disconnect the HDMI cable, the apps go back to laptop screen, taskbar becomes a normal (not icon only) taskbar but the apps but not appear in the taskbar.

Comment 5 Nuno Costa 2020-12-24 18:54:35 UTC

To add that I have the taskbar to only show applications that are on that specific screen(Only this setting is enabled >> “Show only tasks: From current screen”).

Tested on Fedora 31 and 32 and issue was there.

After upgrade to 33, I can’t reproduce the issue anymore. Seems to be solved.
