Thanks much. I will give the Hyper-V a try. is there any tool that could convert a VMWare to a Hyper-V?

Interesting. Ticked Accelerate 3D graphics with 1G Graphics memory is even worse than unticked. I'm using Lenovo T560 i7-6600U @ 2.60ghz, 32Gb ram, SSD, 4K resolution and graphic setting: 2 VMs, the one with Delphi 2007 installed doesn't have any issue, but the one with Delphi 10.4/10.3.3 installed is having the issue, never used Snapshot.

Thanks much. It indeed improves, but the scrolling issues I described are still there.

@ A.M. Hoornweg, Thanks. Are these VM Windows settings or the host's?
