I'm having issues with scaling on Wayland with Fedora 33 (Radeon 6900 XT, kernel 5.10.15-200). I've got double 4k 27" monitors.
Scaling changes the size of UI components correctly, so setting it to 200% in gnome settings makes everything appear twice as big, but most of the programs I'm using detects scaled resolution (UHD/2 = FHD) but not the scaling factor (2x).
Effect of this is that a program is rendered in FHD instead of UHD and it makes it blurry to display on UHD monitor. I've run through the ArchWiki for HiDPI but nothing seems to work. Below is a screenshot that compares font rendering of Firefox and Visual Studio. Most of the programs I'm using are blurry with wayland scaling (e.g. Visual Studio, Android Studio, Slack, Mailspring)
Any known way to solve it or people using wayland with HiDPI are not bothered with blurrines?
