(In reply to James Kitchener from comment #0) > Underlying problem or a consequence of my ancient graphics card? Thanks for the report. This signifies that our GL symbol detection code failed. We detect that your GL driver should support transform feedbacks but we can't find the symbols exported by the driver. A quick look at the transform feedback detection code turns up an error. Are you able to apply the patch I've attached to this bug and report back if it fixes the assertions?
