This is lower in the code then Gmoccapy - affects Qtvcp and Gladevcp haven't heard about an AXIS report yet. I may have more details in the qtvcp section of forum...

[c-morley]

I can't find it. IIRC they changed something in the underlying openGL python library (something we can't do of course) but it might give us a clue. I'll post if I find it.

I can reproduce this. affects all UIs that use gremlin.
