The symptom is video garbage or just total black windows. I haven't been able to tell where to file a bug about this, but today I tried the same old test with 4.3 and the qmlscene runner from qt5.1.1 (instead of the 5.0 shipping with Ubuntu Saucy), and I got an assertion failure in the guest additions. I've attached a screenshot showing the glitch and the minimal QML example that triggers it. I'd appreciate any suggestions on a workaround, as I need to use QML, and thus end up using the virtual machine in the excruciatingly slow software-rendered mode." defect closed 3D support VirtualBox 4.3.0 obsolete Linux Mac OS X
