I enabled Vt-d on my core 2 duo machine, but this has a side effect of blurring my screen and windows 50% of the time. I'm attaching a screenshot to give some idea. Does anybody know what the problem might be. And should I report this as a but to microsoft and how? Please note that the problem is on the host desktop, and not the guest. I haven't even opened my Virtualization app, let alone start a VM.
To me that looks like corruption in the display memory (though without seeing it live I can't be 100% certain).
Does the problem persist if you reduce the resolution of the screen?
