My experience is the same. I mostly use macOS on the desktop, so I am used to Lo/HiDPI screens to work together. On my Linux workstation, I tried several desktop environments, but GNOME on Wayland was the only environment to nail it 6-12 months ago (there may be improvements in other desktops now). HiDPI worked with Wayland and X11 applications and I could just use both screens with different DPIs, drag windows between them without oddities, etc. It's a shame that they nailed this, but decided to remove menus, desktop icons, system tray icons, etc. GNOME could have been a great competitor to macOS and Windows, if they actually talked to real-world users. I wish that they had an UX steward like Sun Microsystems back in the days.
