My Question or Issue

Hi there, I've blurry letters within the Desktop-App on 32° display. I only have this problem in the original scaling. If I zoom the display up to 125% the letters are sharp as.... I never expierienced this on a 4K screen and before on 22" LG Display. So, I'm afraid it's the display but Spotify is the only app with that blurry letters.
