My own build of Blender that OSL support is enabled crashes on startup
in Virtualbox.
Attached a backtrace.

Confirmed in Mesa again. I'm not 100% sure this is only the fault of
compiz/decor. I've just reproduced a similar crash with LLVMpipe, but
slightly different below drisw_update_tex_buffer.

Would it make sense to keep the pixmap allocation in the decorator, but move
all pixmap frees into the decor plugin? That should ensure any pixmap passed to
decor is still valid. Assuming that is the problem.

Yes, that will work, however we'll need to be careful about not leaking
in the decorator in that case. That will probably involve compiz
creating a session window as well for the decorator, which isn't a
difficult task

Assigning to smspillaz. He knows a lot more about the decor texturing

you work together to figure that out? Thanks!

Forget what I said in #12 (changing screen resolution didnt stop it -
still happening as of Bug #1044454 [unity 6.2.0-0ubuntu4 ; Ubuntu
3.2.0-12.21-generic 3.2.2 ). Although I agree with jdreed in #13 it is
way more stable than before.

Possible work around: Changing screen resolution ??
I first encountered the problem when I was in the process of installing a big
pile of
updates using aptitude... (see Bug #1040774)
Then the UI began behaving all wacky. Everything started flashing
black every time I moved the mouse.
I had the same situation described in comment #12, and changing screen
resolution, even down to 1024x768, didn't help much. It did reduce the
flashing and black screen, but not enough to make it really usable. So
I think that reducing screen resolution makes the problem less bad,
not actually
