Shaking cursor with EnableGammaRamp = true

Thanks.
Would you mind trying at 60Hz? It's selectable in advanced monitor settings. I can explain if you don't know where to find that.

When connected to the DisplayLink adapter Windows does not give me the option for 75hz, only 60. So I have already tried that.

Would you please be able to upload logs? The third link in my forum signature shows the tool and steps. Only support personnel will be able to access the attachment.
I'd like to see monitor details (timings), and available modes. I found tests we made a couple of years ago and now understand why 60 Hz has the trembling mouse cursor.

I had this same issue with a shaky cursor once I enabled this flag and it was resolved by moving my refresh rate from 75hz down to 60hz. However, with this flag enabled, my mouse click was registering about one cursor-width left of where I was actually clicking. This only happened on the two external DisplayLink monitors - my internal laptop monitor was file. Removing this flag and unplugging/replugging the dock with the monitors resolved it and now my clicks are accurate again.

Is there a workaround for this issue as part of the flag too? I'd like to enable the night mode on my monitors but these bugs are really odd.

By flag do you mean registry change for EnableGammaRamp?

If yes, can you please gather logfiles How can I report Windows issues to DisplayLink?
