Multi-monitor high-DPI will probably never work well in Xorg, but most Wayland compositors support it just fine. I switched to Sway a few months back and it's great. Unlike in Windows, when a window straddles a high-DPI and lo-DPI monitor, it's not big on one monitor or small on the other. It stays the same virtual size on both and the window contents quietly re-renders itself in high or low DPI when it's dragged between them.
