SUMMARY
When switching between display servers, this can be quite frustrating when the default is significantly below the ideal value.

STEPS TO REPRODUCE
1.  Set as 75 Hz in Wayland.
2.  Switch to X.

OBSERVED RESULT
My refresh rate reverts to 60 Hz - the default.

EXPECTED RESULT
My refresh rate should not be modified.

SOFTWARE/OS VERSIONS
Operating System: Fedora Linux 40
KDE Plasma Version: 6.1.3

ADDITIONAL INFORMATION
If this is because the available rates can differ, then please verify whether the current rate from Wayland is available in X before reverting to the default otherwise.

Screen settings are independent between X11 and Wayland for technical reasons, sorry.

(In reply to Nate Graham from comment #1)
Thanks anyway. That makes sense. Is it that it would be complex enough to implement that it wouldn't be worth the time, or practically infeasible? I could always try my hand at it if it's just a matter of checking whether a value in a file matches a value in another.
