I was unable to reproduce on my mac. Could you please specify your model, including screen resolution, and OS version?
I am still experiencing the same issue. I am using a 2016 Mac Book Pro. MacOS vers: 10.14.2, Proximity version 3.0.3. My screen resolution on my Mac is the default: 1440x900.
Major lag with the cursor. The cursor also does not appear in the same place on the shared screen, as it is on my laptop.
In my case the hardware is Macbook Pro ( 13-inch , 2016, Four Thunderbolt 3 ports ) , also Alex who responded to this thread has tried the 1280x800 resolution and experienced the same issue.
I just tried to replicate this issue and I not seeing the same behavior. Could please let us know more details about it, do you have ant type of lag when moving the cursor?
