Screen refresh rate is not restored after disconnect

[schoerg]

Bug Description

In Rustdesk you can change the resolution of the remote desktop, but after disconnecting, the remote resolution is correct, but refresh rate is now set to 60 Hz instead of 120 Hz which was set previously.

How to Reproduce

Fedora 42, xfce, Rustdesk 1.4.2, Windows 10 is connecting.

Set display refresh rate to 120 Hz, with resolution 2880*1800 (native resolution)

Connect to Linux-Desktop, change resolution in the Rustdesk menu, resolution changes for the session.

Disconnect, remote desktop switches back to original resolution, but now with 60 Hz.

Expected Behavior

Refresh rate should also be set to the previous value (in this case 120 Hz)
