segfault in when changing display modes

Reported by: alphapapa Owned by:

Version: VirtualBox 4.2.8 Keywords: crash segfault libqtopengl
Cc: Guest type: Windows
Host type: Linux


I just upgraded from 4.1.something to 4.2.8 because it was crashing when restoring a saved machine state. Now it often crashes when I switch between Scale and Seamless modes. This was never a problem before upgrading to this version.

It's a Windows XP guest and 2D acceleration is enabled--3D is not.

Please try disabling the 2D Video Acceleration (on "Display" pabe in VM settings GUI) and see if it solves the crash.
