Thanks a lot for the response!
Unfortunately, downloading the newest update did not work.
I've attached a video of what happens.
It also only seems to happen with my webm videos, and not 100% of the time.
Could it be something with my installation of VLC? I just tried updating it, but that didn't seem to help.
I use AEON MQ7 sometimes, and that doesn't crash when I have VLC selected, seems like it's just this theme.
