As the last step to isolate the issue, I've created a trivial GL-based TPP and was NOT able to repro after trying many times. I assume at this point that the Qt QuickSceneGraph Renderer the actual TPP uses is doing something funny.
I am off the next couple of days and if anyone wants to try the TPP is in silo 80 (https://requests.ci-train.ubuntu.com/#/ticket/1187). Please use the packages with the '15.04.20160330-0ubuntu1' tag as 'citrain device upgrade' picks up the older versions, probably because not all 'arch'es built successfully the last time.
At this time, I'll remove myself and Mir from the bug, as I am not familiar with the QSG.
