No, we won't put a hack in to disable dynamic buffers for this case. This may be an inconvenience for users that use Xinerama, but it would only take away pressure to get the actual bug fixed and cause pain for further development at some point.
Fair enough.
It's pretty hard to catch a bug like this in a stand-alone test case, so I'd prefer to give a bug report based on Unigine Heaven a try first.
I submitted a bug report, right after testing with updated drivers (280.13 just landed in testing this afternoon), no change however.
I'll let you know should I get a response from that bug report.
