I seem to be randomly having polka dots appear on my UI components, but specifically not the abilities in the bottom right and the ultimate charge. However, i do seem to get them in the black background of my player icon in the bottom right whilst in game, in the kill feed and on the actual hero pictures in the hero select screen. This seems to appear at random and sometimes even only covers half of say a kill notification in the top right. I did also experience it on the ptr but thought nothing of it as i only played on it briefly so only thought of it as my game not loading up properly. Also it doesn’t appear all of the time. However once it has started i have to restart the game as it won’t stop.
The pattern is not just a dot every few pixels but the pattern does seem to repeat itself, also sometimes the pattern differs between screens like the hero select and the actual game play screen.
Hope this is helpful and you are able to fix it and maybe some other people might be having the same issue.
