I noticed that with the latest Sonoma 14.4 update, my graphics card AMD Radeon RX 6900 XT is now supported with variable refresh rate. Since my monitor supports up to 144 Hz, I have the option to select the refresh rate as "Variable 48-144 Hertz." My only issue is that the screen flickers every now and then. I know my monitor supports variable refresh rate, so I don't know where the disconnect in timing is between graphics card and monitor?

Checking if someone has enabled variable refresh rate and noticed any flickering? When I simply select the 144 Hertz rate, the random flicker stops.

It doesn't flicker on the second monitor which is set at 60 Hertz.
