Hey @Aray, still seeing the cursor freeze for 1-2 seconds on my Surface Book 2. Followed all instructions I could find in this and other forums.. no luck.
The fact that it is prevalent across Surface Book/Pro, and affects me with both the trackpad AND mouse leads me to think it's an OS-specific code issue, maybe? Like some bug in the NT kernel is lagging mouse user feedback.
Microsoft please help, this has been a problem for my Surface Book's entire life and across a full reinstall of the OS!
