Xming on Windows isn't exactly a walk in the park either -- I'd still rather use the native, proprietary build of VSCode on a proprietary OS with the SSH extension if I'm on a high-DPI screen.
Many many many apps on Linux still have massive issues with DPI, especially with mixed-DPI environments (which are no longer an edge case, they're the Common Case with a laptop attached to a monitor).
Even accessing machines remotely via Xrdp has huge issues because once you create the session with a certain DPI, logging into the session from a different DPI machine means you're stuck reading either extremely tiny or extremely huge text
They are totally an edge case.
If you care about hidpi why do you still have a bad external screen?
If you don't care about hidpi simply set a lower resolution on the one hidpi screen.
Its really not, only Linux makes it that way. If its done right (as it is on mac, and to a _very_ slightly lesser extent, Windows) there isn't 'blurriness' at all. One monitor will just happen to be sharper than the other.
I work every day with a 4K monitor and a 1080p monitor side-by-side and it works well. Linux couldn't handle it in any configuration, especially with mixed Intel integrated+nvidia graphics, but Windows is a champ.
Wayland+Intel is working quite well in my mixed 4K+1080p setup. Qt apps are handling like a champion. Gtk seems okay too.
Obviously it's not so great with Xwayland, definite blurriness there. But to compare, the only workable X11 setup was one that ignored my 4K screen entirely and the whole thing was blurry.
? there's an enormous effort to fix the blurry chromium on wayland (and by extension electron and vscode), codenamed ozone, and vscode make me painfully aware of it every day.
That’s an effort to have Chromium work natively on Wayland. It works just fine on X.org and even under Wayland with XWayland if you use something like ChromeOS’s Sommelier or just set window.zoomLevel/--force-dpi-something=2 (and not have XWayland windows scaled).
I mean, it's just an X server for Win32 - I'm assuming it's a fork of Xming, just polished and neatly packaged for usability. It's fast enough to use interactive apps like text editors.
Just for fun, I tried loading a Word document in LibreOffice - I can see the redraw lagging behind scrolling, but it's still usable enough even when typing.
