3D acceleration in Linux/Ubuntu causes UI bugs and system crashes

[f456]

host is windows 7 sp1 x64 laptop with a nvidia graphic chip. guest is a ubuntu 14.04 x64 (guest additions installed).

I am using 4.3.12 because there are just too many bugs with 4.3.14, but i can reproduce it in 4.3.14 aswell.

Two problems that hit me in the face (there are probably more):

1) QtCreator uses OpenGL in its welcome screen, as a result wired UI bug appear, where the welcome screen is before the rest of the application. Screenshot:

2) When terminating some opengl application (like QtCreator), it hangs the entire system and i have to do a hard reset(!).

To reproduce both problems, download the the Qt5 online installer for Linux x64 and install the default configuration (QtCreator + GCC libaries). Then start QtCreator and observe above defects.

Workaround: turning off 3D acceleration resolves both problems.

However, that is not an option if one wants to use the Ubuntu desktop.

I have similar problems using VirtualBox 4.3.14 with both Ubuntu 14.04 (64 bit) and Fedora 20 (64 bit) as guest OS's, using Windows 7 64 bit as the host. I have found that if you run *any* opengl based application, there are lots of rendering errors, and the virtual machine will crash upon attempting to do a controlled shutdown in the guest OS. Occasionally, the virtual machine will crash for no apparent reason.

An easy example is the pcb package found in both Ubuntu and Fedora distributions.

Please reopen if still relevant with a recent VirtualBox release.
