[vbox-dev] OpenGL useless

Host = Ubuntu 12.04 LTS 64 guest = any late model Debian type guest that
uses Gnome3 and the DTM does not matter.
After years of building from SVN I have finally come to a place that I
can not deal with.
I have tried building from SVN on just about every debian distro I can
find and it just does not work properly. I see no build errors (well
other than the ones I always see) but I must be missing something. If
you turn off 3D acceleration in the guest settings you can actually use
the guest, but at a cost of a 30+% hit to the processor due to LLVM
Turn it on and the second you try anything that uses OpenGL the guest
freezes at 100% cpu. Sometimes you can (host+backspace) and get to a
white screen but you still need to kill the guest to recover.
Now looking at the log I see the following line spamming the log 3 to 4
times a second, until you kill the guest.
OpenGL Warning: glXMakeCurrent(0x7fe58c099230, 0x5000008,
0x7fe58e6d9828) failed! (winId 3, ctxId 2)
This all started for me a little more than a month ago with a CD insert
issue that I finally tracked down to 3D acceleration. Since then it has
been getting worse to a point that the builds are useless. I was told
that you could not replicate this so I figured it had to be due to the
release I was using to compile with and built another Debian 6 box to
build on but it is exactly the same with that. I have also looked at the
code to see if you are using a new package but I can't seem to find it.
So I guess I have to claim stupidity and ask if you can point me to a
sane place to go to fix this? Or is there something I need to do beside
shot this thing and move on.
