Default Trembling cursor

Hello,
since installing 9.0 the mouse cursor is trembling continuosly.

I have a 3 screes set-up: Laptop screen + 2 screen via displayport connected to Dell Dock

If I move the cursor to the display not attached to display link , the trembling stops.

Only way to stop trembling, is to enable pointer trails (that I believe disable hardware cursor drawing), but this reduces performances.

attached diagnostic logs.

Thanks.

Hello Luigi,

Yes, I had seen your feedback and got the issue prioritised but hadn't taken the time to let you know...

We've seen an issue at specific pixel throughput linked with another code change. As you clearly identified, the hardware cursor has major performance advantages, and that's why we have disabled the other changes.
The pointer trail does force a software blended cursor on the computer. We also have a registry switch to force disable the hardware cursor (LowLatencyMouseCursor set to false in HKLM DisplayLink Core).
Thank you for taking the time to report this!

Kind regards,
Alban
