@cinebox @marcan Windows lets programs declare if they're per-monitor DPI-compatible. If they aren't, the program will render at primary display's DPI, then bitmap-scale on other displays; unfortunately this is slightly broken if you maximise such programs on non-primary displays – somehow Windows in this case manages to randomly not maximise the window completely (you get 1 pixel wide area at the top where clicks fall through, which is great when you want to close or unmaximise such window, and you actually do that to whatever was behind it).
