Not only that but it started happening in video too on firefox and that is really horrible.
Sounds like you're referring to https://gitlab.freedesktop.org/xorg/xserver/issues/924 ? I thought we'd just established that's not using PRIME, in which case it's probably not directly related to this.
Yes. I will reopen that bug again as you closed it but well its not solved yet.
