Display problems when maximizing a full-screen Gnome VM when 3D acceleration is turned on

[Darrin]

Host : VirtualBox 4.1.16r78094 running Xubuntu 12.04 (XFCE4 desktop) This is a 64-bit AMD host with 6 cores and 16GB memory.

Guest : ubuntu 10.04 running Gnome desktop

Problem : Running VM in fullscreen mode, minimize to go the host desktop. When I switch back to the VM again, I still see my host desktop. If I click, anywhere on the desktop, then I start to see part of the VM's desktop. If I click down in the bottom-right corner of the screen, then about 90% of the VM desktop appears. Prior to release 4.1.16, the VM desktop did not appear upon clicking. Bug 10503 sounds similar https://www.alldomusa.eu.org/ticket/10503 And fixes for it MAY contribute to the improvement. Running a tail -f on the Vbox.log file shows nothing at all is being written to the log file while this is happening. I'm attaching the log anyway.

To work around this, I can EITHER A) turn off 3D acceleration or B) Switch the Guest to the XFCE4 desktop.

The VM is set up as follows : Base memory = 3250MB Processors = 2 Video Memory = 128MB Acceleration = 3D Remote Desktop = Disabled IDE Controllers have "Use host I/O cache" enabled Audio Driver : PulseAudio Audio Controller : ICH AC97 Network Adapter : Intel Pro/1000 MT Desktop (NAT) USB (0 active) Shared Folders (none) Drivers - proper video driver is installed on host (Nvidia) as well as guest (via guest additions) and all packages are up to date on host and guest.

This should be fixed with VBox 4.3. Please give it a try, and re-open if needed.
