If they somehow managed to patch it then that's awesome, what does this say? I remember having a similar thing where it said one refresh rate but actually drew another.
It says "UNSUPPORTED: VSYNC is not available on the Linux platform." and runs at a stuttery 133 fps. This test shows 144 Hz: https://fpstest.org/refresh-rate-test/ The Nvidia settings app shows 144 Hz + VRR are active and I can see that the cursor is rendered at >70 fps.
