It keeps disappearing completely, showing the desktop underneath, and it's doing this in both full screen and windowed mode. Most of the time this is just for a fraction of a second, but it's occasionally been almost a full second long, which made me think virtualbox had crashed the first time I saw it. 2.2.0 was fine, however I have just done a major update of my system, so isolating the cause of this may be tricky. In one step, I upgraded: Ubuntu 8.10 -> 9.04 VirtualBox 2.2.0 -> 2.2.2 And as part of the upgrade I also installed the latest ATI Radeon Drivers for Linux (v9.4)." defect closed GUI VirtualBox 2.2.2 fixed flicker disappear Windows Linux
