4.2.1 and 4.2.2 guest additions 3d support framebuffer issue

[hootjr]

There are issues with 3d support (both in OL6 and in Windows7) on 4.2.1 and 4.2.2 r81494.

4.2.1: =====

• Linux Guest - If you enable "Desktop Effects" from Gnome in OL6, it will work just fine (wobbly windows and all), but the frame buffer is pushing the image up maybe 20-40 pixels.
• Windows Guest - The same is true in Windows 7 with the WDDM driver-- enable Aero seems to work just fine with effects. But the image is pushed up 20-40 pixels.
• NOTE: if you go to "Full Screen" mode with either Gnome or Windows 7, everything seems to work just fine. So this only has to do with "windowed" mode.

4.2.2: =====

• Linux Guest - "Desktop Effects" don't seem to even allow you to enable them from Gnome anymore with the new guest additions installed.
• Windows Guest - still the pixel issue.
• NOTE: "Full Screen" mode still works with Windows7, but does NOT work with Gnome.

I am running OSX Mountain Lion 10.8.2 and Virtualbox 4.2.2 r81494.

Could you check wheter the issue is fixed with VBox 4.3 and 4.3 Additions, and if not, please attach a VM log here.
