Weird pixels on walls etc (Grand Theft Auto 5)

In short, guys, this crap appeared not so long ago, maybe a month ago. I went into GTA just to play, periodically I replay the plot. but when I once again went into the game I saw this and my eyes came ***. I think you will see if you are sitting with a PC, but you can also see it from your phone (pay attention to the wall of the hospital on the left and to the road) How to be? What is it and how to fix it?
