I haven't got a VM to play with but I do use Win7 under VBox, yes.
Stuff to consider: * For Windows guests, 2D & 3D acceleration are separate options. Both are available. Is either on? Try toggling their status? * Do you have the guest additions installed? If not, try it. * If they are installed, have you upgraded them to match the host version?
Liam, Thanks. Yes I've already tried both 2D and 3D acceleration options (makes no difference). Since I use rdesktop to access the guest, the graphics performance isn't really tied to the acceleration models. I have installed and reinstalled the current versions of Guest Additions, no change. (I always update Guest Additions with every host version update) This is a really weird issue that seems tied to how vbox 6.0.6 behaves with the --headless option. It's almost like there was a change to the network communication that now inadvertently synchronously blocks waiting for each redraw request to complete where before it was handled in a non-blocking manner. (I'm guessing here -- but that is about the only code/change based logical guess I can come up with that matches what I'm seeing. It also explains why large block-redraws seems less effected than smaller line-by-line updates of the terminal) -- David C.
