Multiple Monitors with Gnome 3 (Shell) Renders Incorrectly

[Steven Ercolani]

Fedora 15 x64 that includes Gnome 3 (shell) and when I enable multiple monitors (2), the overlay that Gnome does messes up the display. Parts of the screen are black and parts of the display go fuzzy.

I've attached a screen capture of the displays to give people an idea of what's going on. As you can see, the one display shows some of the display correctly, but most is just blue and black boxes, and the second display is simply white. In full screen mode, both display are similar to the first display in the image.

Image shows one window for each monitor and how the display is not usable when using Gnome 3 as a guest in a dual monitor configuration.

I see the same problem.

Still broken with VirtualBox 4.1.0.

Subscribing to this bug. I am seeing the same issue with Ubuntu 11.04 and Gnome 3.

[Steven Ercolani]

Verified this is still an issue in version 4.1.4.

[leonbnu]

Could you check whether the issue is fixed with VBox 4.3 and 4.3 Additions?

[Michael]

It is still broken with VBox 4.3 (and new additions).

[misha]

Could you attach a VM log for this issue please?

OK. VM log attached.

I see this with VBox 4.3.6 and Fedora 20 x64. With 2 monitors selected in the VM settings, I get completely blank screens after the VM boots.

If I switch to fullscreen mode and back I do see the VM login screen briefly before it does black again.

I appear to have the same issue with Win 7 64 bit guest and Ubuntu 13.10 64 bit guest. Login screen renders fine, but after that, just black.

Disabling 3D acceleration works around the problem, but results in a slow desktop.

More info: seems to particularly affect performance when using full screen mode. When not, performance seems fine. When I use 3 screens, perfomance grinds to a halt in full screen as a result of using the llvmpipe stuff.

Ubuntu 13.10 64b on Win 8.1 64b 3D acceleration still failing.

Please reopen if still relevant with a recent VirtualBox release.
