I install clean Windows 7/8/1/10 installations. I then install Guest Additions with the default graphics driver, and restart. For Windows 7, I manually enable Aero. For Windows 8.1 & 10, this is automatic. Everything is fine until I start a Windows Installer program, or try to uninstall certain programs. At this point the display starts to become pixelated and discolored. Each time I change screens or move the cursor the pixilation becomes worse.
SPECIFICS: The only way to get rid of the pixilation without restarting the VM is to restore (un-maximize) and maximize the VM display window. I started noticing this about a month ago. I tried rolling back the VM additions and graphics drivers to the versions when this wasn't yet a problem, but that does not fix it. This occurs in Windows 7, 8.1, and 10, in both x86 and x64. This problem can be avoided by disabling Aero in Windows 7. HOWEVER, disabling Aero transparency does NOT fix Windows 8.1 or 10. This is not remedied by changing the amount of VM graphics memory, 2D settings, or 3D settings. I tried ALL combinations of enabling and disabling these. HOST GRAPHICS: NVidia GeForce GTX 970M HOST OS: Windows 10 x64 LOG: Attached. Starts at VM bootup and ends at first signs of this pixilation.
