Yep keeps happening for me too... black screen sometimes and total crash to desktop after some games...
my partner as well but he gets then all.... and the invisibility thing and other issues too.... so its not as noticeable
To be honest we have now got to the point where we barely even talk about these things even the new ones, we just say "oh theres another thing.... blah blah" or "oh look that blah blah blah issue is back for me" and just deal with it... if we can... reboot, etc etc.... pretty used to it now... its been like that since beginning of Founders (although it was much worse at the beginning)
@ippigand we don't have Nvidia drivers so cant be that, at least for us
