Status changed to 'Confirmed' because the bug affects multiple users.

That line will always be present in Xorg.*.log when VirtualBox's 3D passthrough is in use. The reason is that our DRI driver implementation is not complete, and that is not likely to change in the near future, due to lack of developer time and more pressing issues. We have actually had one or two people from the open source community interested in contributing to our drivers but so far no code has materialised.
