Hey. I have this problem. When I first-run my newly built standalone game, everything looks normal. However, when it quits and I want to play it again, all the textures turn blurry. I have even tried building it on mac, but the problem persists.
I have one atlas for all sprites that is 4096x4096.
Also I have found, that when I run the game normally, then once in Unity Editor and the normally again, the textures are normal for that run.
Any help?
