No need to test X - that will work fine, since we were reporting the smaller cursors on that kernel. So I think we have definitive evidence that at least all Kepler doesn't do 256x256 (and it's not just some bug in the display macro rework that got introduced). And unless I'm blind and don't see the corruption, Pascal seems fine. Question remains for Maxwell1/2 GPUs. Unless someone has immediate plans to test on those, I'd recommend bumping the minimum for 256x256 being reported to Pascal, and doing 128x128 for Kepler / Maxwell. Simon, Lyude -- thoughts?
