When I first tried out Zelda in Dolphin yesterday, I noticed these strange squares at the top of the screen. There are also some black lines flashing irregularly in certain walls or floors, which don't show up in screenshots.
When I started the game today, everything looked fine and I could play for about one hour. Then all of a sudden, the artefacts made their return. A restart made them go away, but they appeared again after a few minutes. Now I can't get rid of them at all. Even when I restart, they are there right from the beginning.
I didn't change settings or anything during that time. Always used r7719 and felipepl's settings. Did somebody else notice this issue on their PC? Since I'm using the same settings as everyone else, is my GPU dying or something?
