Hi!! I haven’t used Krita in a few days and when I came back the UI was much bigger (I assume because of the update). I’ve had this issue before and disabling HiDPI support fixed it, but this time it’s already off. Screenshot from 5 days ago versus now: [image] [image]

Are you using Krita 5.3 or Krita 6.0?

Thank you! I ended up switching from the package I had installed with pacman to the appimage so I could try this. I didn’t have the problem in the first place with the appimage.

6.0.0 was what I was using, but the appimage which doesn’t have the problem is 5.3.0.

The AppImage for that is here: https://invent.kde.org/graphics/krita/-/jobs/4212643/artifacts/file/_packaging/krita-6.1.0-pre…

Hello, I’m sorry for not replying sooner, I didn’t think to check this forum again! Anyway, I downloaded the AppImage (pretty sure that’s what I was supposed to do, but correct me if not) and I don’t think it seemed to be fixed; disabling/enabling HiDPI didn’t change anything. I also got this error …

Yes, the fix didn’t actually work since Qt6 removed the regular way to disable high-DPI scaling. A subsequent attempt with a different way did: https://invent.kde.org/graphics/krita/-/jobs/4216293/artifacts/file/_packaging/krita-5.4.0-prealpha-7c47712cb9-x86_64.AppImage You can also fix it by setti…

I set the environment variable for the AppImage you sent earlier and it’s fixed again. Thanks for your help!
