SUMMARY I'm using manjaro, running with kernels 5.15 and 5.16 (different desktops), with multiple screens, panels on top and bottom, and with global menu, digital time, weather, system tray, and lock/logout widgets. When rapidly switching between virtual desktops latte-dock crashes. I'd like to report the backtrace but I am not experienced enough to do so, specifically I'm uncertain about the steps described in: https://wiki.archlinux.org/title/Debugging/Getting_traces. STEPS TO REPRODUCE 1. Install latte-dock 2. Maybe have the widgets as described above. 3. Quickly switch between virtual desktops. I switch using shortcuts. OBSERVED RESULT Latte-dock crashes. Running latte-dock through krunner often makes panels appear again. EXPECTED RESULT No crash. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.23.5 KDE Frameworks Version: 5.90.0 Qt Version: 5.15.2 OS: Manjaro Linux x86_64 Kernel: 5.15.19-1-MANJARO Packages: 1579 (pacman) Shell: bash 5.1.16 WM: KWin

I haven't experienced any crashes after clearing the cache of latte-dock. For now, close the report and if it starts happening again I can reopen it. Thanks for your feedback.
Created attachment 147544 [details] ddd backtrace for latte-dock Latte-dock began crashing again. I ran with ddd and attached the backtrace as an image.
I've added an image of the backtrace as the bug started occurring again.
(In reply to jendal from comment #5) > I've added an image of the backtrace as the bug started occurring again. crash report does not contain any latte code reference... this is starting to feel more like one of your applets is crasing or your graphic driver issue. I personally do not user VDs at all and use only Activities . In my system such crash never occurs.

This has affected me for along time, and when needing to switch desktops often Latte Dock would crash so frequently it became useless, sometimes multiple times within a few minutes. I narrowed down the problem to the Latte Tasks widget (even with no other applets Latte would crash). I use a Unity-style setup with a panel on the left, so my workaround was simple to stop using Latte Tasks and use KDE's Icons-Only Task manager. Then latte-dock is fine and I haven't seen it crash in over a week. I did try to use Latte Tasks but using the default "Plasma" indicators, and that seemed to work fine too. Switching the indicators to "Latte" soon brought back the crashes, but then going back to Plasma didn't make the problem go away after it started (hence just going back to using the Icons-Only Task manager).
