I use lattedock instead of the plasma panel as it decouples the panel from plasmashell and on Wayland my desktop is more stable thanks to this. However lattedock is crashing from time to time, usually it can restart but not always. I'm not sure what exactly is the root cause (sometimes it might be an xwayland application, copying network files or even network changes). But there is no trace back. I've tried to use lattedock from git, but there was no real difference. STEPS TO REPRODUCE 1. Use lattedock on Wayland 2. It will crash after starting some apps OBSERVED RESULT lattedock will crash from time to time EXPECTED RESULT lattedock is not crashing SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.17.0 KDE Frameworks Version: 5.63.0 Qt Version: 5.14.0 Kernel Version: 5.3.7-arch1-1-ARCH lattedock 0.9.3
Crash report?
too generic title... more info are needed
Thanks, I wish I could provide more details, but the following is the only output I got when starting latte-dock from the terminal: $ latte-dock Warning: QT_AUTO_SCREEN_SCALE_FACTOR is deprecated. Instead use: QT_ENABLE_HIGHDPI_SCALING to enable platform plugin controlled per-screen factors. Icon theme "gnome" not found.

[1] Beendet latte-dock ###translation: closed [2]+ Angehalten latte-dock ###translation: stopped These logs do not tell anything useful to me. I use lattedock on 2 different systems and on both it is crashing and restarting from time to time. If you tell me that it is working absolutely stable for you on Wayland, I might have a special config or it is Arch Linux related... or could it be that plasmashell will take latte down?

Wayland is general is unstable in general with Plasma, it is considered in Beta state even for Plasma. Close Latte and use Plasma panels with the same applets you are using with Latte, after a while you will probably get the same crashes. Qt libraries still contain many wayland issues even with upcoming Qt 5.14 . My approach is the following for the Crash report found from KCrash in the systray when Latte is crashing, if the crash points Latte code then I am trying to fix it as possible. But if the crash report points to Qt/graphic drivers or Plasma then I am not trying to fix or workaround anything any more... When the Qt/Plasma stack is considered stable in the future then I will try to improve things for Latte implementation in wayland. In my system I dont use wayland... too many issues with Plasma/KWin and Activities are also not working at all which is based my main workflow, so I wait...
I will close this bug. I had some random crashes again and as suggested they point to Qt, the graphic driver or to Wayland. In general lattedock is great, it works really well for me and it is more stable than the plasmashell panel. So I will continue to use it on Wayland too. Thank you
