Bug 2314439

I upgraded from silverblue 40 to silverblue 41 beta and I'm using 200% scaling and now steam detects the maximum resolution on system information as 1080p when it should be 3840x2160p that I'm also using on the desktop, also I can no longer play the games at that resolution, the maximum resolution on steam and its games is now dictated by the scaling in gnome settings, with 100% scaling steam/games detect 3840x2160p, but values above that will reduce the resolution gradually, this didn't happen on silverblue 40.

I'm using an AMD RX 7900 XTX.

The only thing that solved this whole mess for me was this:

GNOME 47 includes an enhanced fractional display scaling feature, which provides better support for legacy X11 apps. This feature is still considered experimental and should only be used for testing. To enable it, you can run the following from the command line: gsettings set org.gnome.mutter experimental-features '\["scale-monitor-framebuffer", "xwayland-native-scaling"\]'


Reproducible: Always

Steps to Reproduce:
1. Install silverblue 41 beta
2. Install flatpak steam
3. Run steam with 200% scaling settings in the gnome control center
Actual Results:  
Steam became blurry and upon further checking the resolution was reported and capped at 1080p on the app and games.

Expected Results:  
There should had been no blurriness and no change in the supported resolutions when using 200% scaling like before.

Sebastian Keller said this on gitlab:

"Fedora 41 enabled the scale-monitor-framebuffer option by default, which will result in blurry X11 clients when using >100% scaling unless the xwayland-native-scaling option is enabled. This seems like an issue with Fedora defaults."
