Happens on my system as well. Prior to upgrade I had set it to 150%, but when I try to change it to 175% for example the apply button is greyed out. The same for VRR, while it applied for Ubuntu Noble Nombat (that said it created artifacts when playing steam game and switched fraction scale back to 100% by itself)
The error is slightly different for me: cc-display-panel[49544]: WARNING: Config not applicable: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Monitor mode size doesn't match scaled monitor layout When turning off fractional scale it defaults to 125% for some reason: cc-display-panel[49544]: WARNING: Config not applicable: GDBus.Error:org.freedesktop.DBus.Error.InvalidArgs: Scale 1.25 not valid for resolution 3840x2160 When switching to 100% I can apply the setting with fractional scale off. When I turn fraction scale back on it spams with: 08:19:14.2066 Gsk[64489]: WARNING: Clipping is broken, everything is clipped, but we didn't early-exit. 08:19:14.2066 Gsk[64489]: WARNING: Clipping is broken, everything is clipped, but we didn't early-exit. 08:19:14.2066 Gsk[64489]: WARNING: Clipping is broken, everything is clipped, but we didn't early-exit. 08:19:14.2066 Gsk[64489]: WARNING: Clipping is broken, everything is clipped, but we didn't early-exit.
