-- Information about the crash:
I tried playing a .mkv video file of a gameplay recording done on Flatpak OBS Studio, when the sound bars were up and glitching with the video immediately upon the program opening. After 3 seconds it crashed.

The crash can be reproduced every time.

-- Backtrace:
Application: Dragon Player (dragon), signal: Segmentation fault
