Bug description and reproduction

I've recently migrated my install from Windows 11 to Docker, and this is the only noticeable issue I've came across. The type of crash that occurs (soft crash that reloads client vs. hard crash that hangs client and prevents reload) also seems to depend on the order of events. I'm unfortunately having trouble reproducing the hard crash so I'm only making note of the soft crash for now.

Soft crash

1. Click thumbnail of a video file in the gallery
2. Click thumbnail of a different video file in the gallery
3. Crash

Video reproduction

Note that the video choice here does not seem to be relevant. The same crash occurs if the thumbnail selection is reversed.

Using MPV in the docker container likely just won't work very well. You should probably switch it to the "show open in external button" option for videos and animations and use something like Hydrus Web for viewing media.

[mmaker-gh]

Thanks, that does prevent the crash which was actually my primary concern. I am already using Hydrus Web to view media otherwise (thanks for that too) -- this really only comes up for me when I have to access the container to manage subscriptions or clean up files, but that workaround will do for now.

I had this problem when the version of the mpv library was too out of sync with the qt library. Welcome to dependancy hell, please ensure your .so and .dlls are correctly stowed.
