the window drawing issues if more of windows os bug and it's still unfixed well I don't expect MS to do something anytime soon... but at least it's reported by many users, so they know it.
It depends, MC uses its own system for window drawing, and sometimes issues can arise from that. Like the infamous white box in the top left corner when starting MC or minimizing/restoring MC from the taskbar that momentarily appears before the window/skin draws that's been reported several times over the years. It's easier to see it with a high refresh rate monitor versus a 60Hz monitor but this one is pretty easy to ignore.
I'll give you another example, which is a skinning-related issue, is that sometimes MC thinks a maximized window for some reason isn't maximized and uses the wrong image (maximize button image instead of the restore image it should use when maximized). What I mean by that is at random, especially when using other full screen apps like games, MC will appear to be maximized (and it is) but it'll appear to be using the button set in main.xml for maximize instead of the restore button which it should be using.
I'll throw one more skinning-related issue at you, my Modern Cards: Acrylic White Edition skin doesn't work with glass effects anymore (I'm using Windows 11, will have to test it in a Windows 10 VM to see if it's just Windows 11). I did some limited investigation and found that any white (#FFFFFF) semi-transparent image no longer shows the transparency when glass is enabled in the skin, instead showing opaque. Other colors including grey and dark work, but not white.
