Dear Maintainer, As In Issue 1475278, the problem seems across all linux distributions.
Adding --enable-features=VaapiVideoDecodeLinuxGL to the list of flags seems to resolve (or mitigate) this problem. So this version (and possibly every release in the future) will require this flag for achieving video acceleration if they don't revert this behavior. P.S: It seems like (possibly) it wasn't right to report this bug really fast without much. I posted this in the hope that it will be helpful. Best regards,
