On my install (Fedora 34, Gnome 40, Chrome Stable) if I run Chrome under XWayland (i.e., if I refrain from giving the flags -enable-features=UseOzonePlatform and -ozone-platform=wayland when starting Chrome) and set Gnome's scaling factor to 200% (gsettings set org.gnome.mutter experimental-features "['scale-monitor-framebuffer']", then using the "display" tab of Gnome's Settings app), Chrome is blurry. Probably it is rendering into a framebuffer, then that buffer is being scaled up such that every pixel in the buffer becomes a 2-by-2 square of pixels on my screen, hence my experience of blurriness. I don't own a hi-DPI monitor, but if I did do you know how to avoid everything's being drawn twice as small as usual without blurriness, i.e., without essentially downgrading the hi-DPI monitor to a normal-DPI monitor?
If (as I suspect) a person cannot do what I asked you how to do, i.e., a person cannot currently configure the set of software I described above to be normal sized on a hi-DPI display without blurriness and without "full Xorg" (i.e., not just XWayland, i.e., requiring parts of X11 that definitely aren't being maintained anymore), do you expect XWayland to be improved so that that becomes possible in the future?
- BrightGlow 5y agoIf this is working correctly on other apps, then it's probable that Chrome's Wayland support is not complete yet.
- hollerith 5y agoNo, it works on no app (that hasn't been modified and configured to speak the Wayland protocol) because of a fundamental limitation of XWayland.

- BrightGlow 5y agoSorry I misread your comment, ignore me. Although I will add: It might be possible that someone gets high-DPI working eventually in XWayland. It's unlikely that X11 will ever support multi-DPI in the same way as Wayland. There is an open MR for something like it though: https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests/733 https://gitlab.freedesktop.org/xorg/xserver/-/merge_requests...
