SUMMARY STEPS TO REPRODUCE 1. 2. 3. OBSERVED RESULT EXPECTED RESULT SOFTWARE/OS VERSIONS Linux/KDE Plasma: 5.8.0-43-generic #49~20.04.1-Ubuntu SMP Fri Feb 5 09:57:56 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.8 ADDITIONAL INFORMATION I use two screen and I have a panel for each them. If I remove the panel that in other screen (not main), Latte Dock starts without crashing at login. If I add it, it's crashing every time. I used once Manjaro Linux and this problem wasn't there. This is the Latte Dock crash report: Application: Latte Dock (latte-dock), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
