Yes, it's true that there are issues. It seems like most Microsoft apps handle multi-DPI well. By comparison, on Fedora 25 (the latest release), the only program I have found that handles multi-DPI is Terminal. Firefox doesn't do it.

Yeah, Windows support is better than Linux for it, but it's still pretty iffy. While IE and a few other things do, even stuff like Windows Explorer and OneNote doesn't handle multi-DPI well or even just runtime DPI changes in general, I'll RDP my box from a 100 DPI system and have my session screwed up when I come back to my system.

If you're making a decision about whether to make a purchase, don't make it unless you're prepared to do it all at once. Stick to ~100 DPI until you can make a commitment to go all at once.
