Win 8/10 seamless

[bqbauer]

Not a new issue, but Windows 8/10 guests still can't run in seamless mode, at least on UNIX hosts. This goes back to Windows 8 and something I read about how they handle the frame buffer (?). I'm probably destroying the actual terminology or reason.

Thanks for the heads-up. Actually there was a fix many months ago (for 5.1.2) but it seems that this fix was either not sufficient or something changed again.
