I would really love to try Krita but as I installed, all menus and icons are very small. After searching through the internet, I have found the cause of similar bugs in many windows applications those are not written to support HDPI resolution and so I end of my wit there. Is there any work around ? TT TT

Well, on my SP3 it's doable. I'm working to make Krita 3 on Windows also hidpi aware, but Krita 3 still is very much pre-alpha.
