Embedded video scrambled on Android

I can’t figure out which is the best sub-forum for this question, so I thought I would start here first. I’ll move it if needed.

Over the last couple of months I’ve been having an issue where after the first 5 seconds or so of playing an embedded video on these forums it changes to diagonal lines from the bottom left to the upper right and everything is scrambled. If I copy the link it plays fine in the YouTube app.

Has anyone else experienced this, and have you heard of a fix? Samsung S10 on Android 11 using the stock Chrome app.

It looks something like this.
