Wrong refresh rate on multiple monitors

[MarcoRoccagliSigma]

Hi there and thanks for very useful driver.
I'm using it in a QEMU-KVM linux virtualized environment where there is a Win11 guest with gpu passthrough.
A cable from the VGA output displays directly the virtual machine, while i'm using the created "virtual monitor" attached to "looking glass" so that i can extend the monitor to the host one.
Everything works correctly except for the refresh rate of the virtual monitor that should be at a144hz but is capped at 60hz (that is the refresh rate of the physical monitor).
If i exclude the physical monitor, and use the virtual one only the refresh rate is correctly set to 144hz (i can spot the difference from 60hz).
Is there any clue on this?
Thanks for your attention

Best regards
