When I press play on the Plyr demo (https://plyr.io/) with Firefox 66.0.4 on Linux, a part of the screen is not updated with movie content. Pressing pause and play fixes the issue. Chrome and IE do not show this behaviour.

I was able to narrow it down to demo.js and I have not much javascript experience but it could be that it has something to do with the thumbnail generation process which is invisible to the user. A minor issue is that I notice that the the text with the gear icon ('Settings') jumps a little from left to right on mouseover. I wasn't able to alter demo.js to overcome both issues I mention here.
