What happened?

Whenever the window of Zen exceeds a width of around 4000 pixels (hard to tell exactly) most parts of the window and its contents are very blurry.

When hovering over a blurry part, this part gets sharp and some other part gets blurry.

I tried following suggestions of older closed issues, which didn't help. Since all relating issues are closed without the issue being fixed, I created a new one.
