Pixilated Square blocks Screen

@Ilois4Is that right. Well my 2nd floor bath is actually directly above that as a matter of fact. The bathtub, too. I don’t usu leave Sims in there - usu in too much of a hurry, but it’s possible. Also could be that there was no one in the tub but the glitch graphic came up because of where it is.
I’m really not too worried about this one, thank goodness, it was more the sudden onset of unplayability. - all these 4 glitches operating at once. But I’ve never had this happen before so I don’t anticipate problems. It’s mainly Sims talking over e/o and, Parties. (Bold, Caps,Italics, 60 font.....👍😉😊)

 
Edit: You’re great to have around, @Ilois4 , you just solve problem after problem. Unfortunately I don’t think I can give you an Accept as Solution because you identified what’s likely causing the bug, but you cannot eliminate it.😉 So I left a Sim in the shower and went downstairs to check on your idea, and couldn’t believe it. There it was. I’ve never had that before. The pixilated screen. So, predictability, anyway. Thank you so much. I won’t report these anymore!
