Comment 4 Thiago Sueto 2021-01-22 00:28:56 UTC 
I can reproduce this, more or less.
While the audio runs fine, every so often a frame updates on the preview, so it's indeed trying to reproduce something.
Selection becomes broken, but it's still possible to open/run files if you set general clicking behavior to open files in one click.
If you resize the information pane containing the video, it creates graphical glitches in Dolphin, especially if the folder contains various files.
Sometimes these graphical glitches may actually cause the preview to reproduce at least part of the video properly (with the rest glitched/frozen).
