Running SubtitleEdit 3.6.6 portable or install eventually results in a UI
freeze, and sometimes a glitchout where portions of the UI are replaced with
blank colored squares/rectangles. The error messages are different sometimes,
but most common is something about h264: get_buffer() failed.

I have not tested this with wine stable.

Here is the program link https://github.com/SubtitleEdit/subtitleedit/releases

Notably, standalone mono (not wine-mono) runs the application fairly well.
