Since you have confirmed in the bug that it happens with Unity 3D but
not 2D then you could add Unity to the 'affects' setting in the bug.
That may get it more attention (or at least different attention).
Presumably you don't see anything useful in .xsession-errors.  It
might also be worth amending the bug description to make clear that it
is likely a graphics issue and include the graphics card info and so
on in the text to that launchpad searches will find it.
