The issue that the VUE (which is a memory slot used by the GPU for a vertex entry) are reused by a second thread before the first thread is complete, causing the first thread to generate invalid texture coordinates and corrupt rendering. That is a hardware read-write hazard bug (or at least I have not found any controls in the EU state to prevent it).
