KDE Plasma Version: 5.22.4 KDE Frameworks Version: 5.84.0 Qt Version: 5.15.2 Kernel Version: 5.11.0-26-generic (64-bit) Graphics Platform: X11 Processors: 12 × AMD Ryzen 5 3600X 6-Core Processor Memory: 31.3 GiB of RAM Graphics Processor: Radeon RX Vega ADDITIONAL INFORMATION After i boot it up with krunner, it's rock stable for the rest of the session. Didn't tried to logout and log in as i have just one user anyway.
It was present in earlier versions too, i think 0.9.8 and 0.9.9 or something (the two versions before 0.10.0)
there was one of such crash fixed in upcoming next bug release. https://userbase.kde.org/LatteDock/HowToReportCrashes
Clearing cache helped for one restart, on next one the bug persisted. Using ddd looks hard, as i would have to start ddd and execute run backtrace before latte-dock - and it's startup crash.I set up env, does it persist over startup ?
On default dock the crash also persist. As earlier, removing QT cache prevent next startup crash.
Without detailed backtrace having a traceable fault is not possible.
