If you have the same mesa packages installed like the OP, and if your issue occurred also after the very update the same way as at the machine of the OP, and if the mitigation that helps the OP also helps you: stay here. If any of these points does not apply to you, I suggest to open a separated topic and assume that you have a different issue, although you are encouraged to mention in your new topic any similarities to other issues/topics (including to this one). However, a confirmation here would be nice so that we know if that can also occur on KDE or not. Otherwise, I would go back to the assumption that this might be somehow linked (caused or provoked) by anything from GNOME
