Other Additional Information:

• Is the issue reproducible on the latest version of Chrome? Yes, same thing on Chromium actually.

I made a comment on #12780, which seems to be similar. It appears to be fixed when disabling HW acceleration...

@71walceli worked for me also, thanks!

Is this still a thing? And does the freeze happens just for a short while, or is it still there even after a hour?
