Description

When you open Visual C++ Express 2010 http://www.microsoft.com/express/Downloads/#2010-All in VirtualBox 4.0.0 r69151, the screen starts to flicker while the resolution is changed from the current resolution to 640x480 several times per second.

The VirtualBox log file shows entries like this:

This issue looks similar to #5597, but is initiated by starting Visual Studio 2010.

Environment

Host: Ubuntu AMD64 10.10 with ATI Radeon adapter. Guest: Windows XP 32 bit, service pack 3 Tried with both single and dual CPU, also with and without 3d acceleration.

Workaround

None yet. But you are able to close Visual C++ Express 2010 with ALT+F4. (Or with the mouse if you are really quick in between the resolution changes). When the program has shut down, VirtualBox is changing back to the normal resolution, and the flickering stops.
