So for a while now I havent been able to use after effects because everything In it's blurry for some reason and have even tried reinstalling several times.
Anyone help me? Picture below.

Thread moved by Xarea (Forum Moderator): to Design & Development - you'll probably get a better response here anyway :).

Are you zoomed in/is your text massively oversized and you're mega zoomed out?

Are your scratch discs clear? I've never had a problem with my scratch discs being full when using Adobe products on my mac, but it's regular on a pc, so it's just an idea.
