Description
Seems likely this is actually a host problem, given the toolbar's impact.
VirtualBox 5.1.12 (also tested with 5.1.10 and 5.0.30, same results). W7SP1 x64 host 8GB, Ubuntu MATE 14.04 x64 guest (kernel 3.13.0-106, X 1.15.1), GA, 2GB. Host graphics: Radeon 7950 running 16.12.1 drivers.
In a fullscreen VM with 3D acceleration enabled, running glxgears (or even just glxinfo) blacks out the entire screen, and regions outside the glx-invoking window don't redraw until damaged. With no changes to host or guest, enabling "Show in Fullscreen" for the mini-toolbar makes the display behave correctly. Very bizarre. :)
I also completely uninstalled VirtualBox and reinstalled 5.1.12, no difference.
The guest WM is Marco (Metacity, effectively) and the behavior is the same whether that's running with or without compositing.
Q: Should I duplicate the logfiles in this ticket, or are the copies in the forum enough?
