-- Information about the crash:
- What I was doing when the application crashed:
Crash happened right after typing in password on the lock screen

- Unusual behavior I noticed:
Baloorunner crashes when opening applicatoin launcher/krunner.
Latte doesn't start automatically, must be started from konsole and gives [Critical : 10:33:06.515515] - "Couldn't find QML Decoration  \"\"" among other warnings (latte-dock -d --cc --replace output at http://0x0.st/oXP3.txt)
After starting from konsole, latte crashed when trying to add a widget to the panel.
Flameshot rarely starts but when it does, it crashes while trying to upload to imgur.

- Custom settings of the application:
Problems started after trying to use playbar2 widget in latte panel (installed via pacman). At first, it showed a blank box when clicked on (but showed the name of the content in the bar), then failed to update when the media source was changed. I rebooted and latte did not autostart despite being in Settings / Startup and Shutdown / Autostart.
