There probably is, but I haven't seen this anywhere else, including other 3D games. Which is a bit strange because according to my understanding many applications create gem objects and bos (buffer objects?). For what it's worth, we can't reproduce it anymore on the bigger machine with the Pitcairn card (on amdgpu), but the notebook with the (integrated) Aruba card (on radeon) is still showing the leak. (Same kernel version.) I can try to collect traces with e.g. bcc, but I don't really know what to look for. If you have an idea what to collect I should be able to carry that out.
