[Missing Category] Fractional Scaling

[klazoklazo]

As someone with both a Hi-DPI built in laptop screen and a 4K monitor, it would be nice to be kept up to date on Wayland's demonstrated fractional scaling abilities in both Gnome and KDE.

Mainly that:

• Fractional scaling is available
• Whether fractional scaling is "blurry" on XWayland apps (EX: 100% -> 150% instead of 200% -> 150%)
• Whether fractional scaling can be disabled on XWayland apps specifically (such as KDE >5.26)
• And whether fractional scaling can be disabled on a per-app basis (such as Windows' DPI compatibility settings)
