I have a weird issue which I am hoping someone will know the answer to.
I am using a Gigabyte Aero laptop (i7-9750 CPU, 32GB RAM, Geoforce RTX 2080 Max-Q)
I also have a 27 inch LG 4K monitor attached.
I use Blender on the external monitor.
If I rotate anything (even default cube) in Blender while the Windows desktop is showing on the laptop then there is a stutter in the rotation every few seconds. If I change it so the laptop is showing Firefox or Outlook then the stutter goes away completely.
I have set my desktop background to pure black, but still the same issue occurs.
Any ideas why this might be ?
