Description
When "Use Unscaled HighDPI Output" is enabled on a Windows 10 Guest graphics corruption occurs. It jumps between rendering the native resolution (2560x1600) and scaling/cropping it to 1/4 that. Mouse movement affects the graphical glitches. Guest additions are installed, Paravirt interface is Hyper-V and 2d+3d acceleration are enabled.

This issue is still valid with VB 5.0.10. Either you enable unscaled HighDPI support or 3D acceleration, but both is not possible.

Same exact issue, still present in 5.1.30. You can't enable 3d acceleration AND Unscaled HiDPI mode together. It's one OR the other. Speed, or fuzziness, choose one.

Could you upgrade to the recent VirtualBox (6.1.2 for ex) and verify that HiDPI feature works fine. Guest Additions should be updated also.
