Hi
I installed brackets on Ubuntu 13.10 guest in a virtualbox 4.3.6 with VBoxGuestAdditions installed. 3D acceleration is enabled and works for glxgears (1700 fps).
On first start I get a slew of warnings and errors concerning OpenGL problems.

Also brackets does not draw itself correctly. The window content is always on top even if an overlapping window should be in front. See screen shot

If I close brackets and try to open again, the window becomes quickly greyed out and does not show any content. I have to reboot the VM to get a proper start again.
