Unpleasant visual effect

I noticed this effect while installing(from the official site). At first it seemed to me that this effect was only for the loading window, but it remained when I started working in the program. I would describe it as sharpening and contrast enhancement + outlining of all elements like button tabs and text.

Without following the troubleshooting steps or filling in the bug report template, the team can’t begin to check on this issue.

Moved to Help for now.
