What kind of windows programs are these? HiDPI is more than a decade old. A desktop application, no matter what OS it is, should always be tested with different scaling factors.
replyOh my sweet summer child. Even software being written TODAY isn’t being tested in HiDPI. Win32 still makes it difficult.
replyI’m not your child, and that’s false, it’s literally one key to change in the settings. That allows you to select the exact scaling factor, not macos’s “more text”/“less text”.
replyHam radio software, both open-source and commercial, is a big thing, and so is many an in-house development in many businesses.
replyI've been fine with Linux/KDE. Even the fractional scaling support is decent.
replyEdit: Guess it depends on the app
