Description timon 2017-08-24 15:10:00 UTC
If I add the the centroid interpolation decoration to any attribute: - the values will be mostly broken (maybe just the first vertex in each triangle is ok? hard to tell) - and there will be block-like screen-space artifacts flickering all over the geometry I can't provide a screenshot unfortunately. My GPU: [AMD/ATI] Bonaire XTX [Radeon R7 260X/360] PCI ID 1002:6658 Running with the amdgpu kernel module, linux 4.12.8.

(In reply to timon from comment #0) > If I add the the centroid interpolation decoration to any attribute: > - the values will be mostly broken To clarify the values for that attribute only, the rest are fine. Also this happens when running without MSAA (can't test with atm).

Hi timon, Can you still reproduce the problem? If so, can you attach a simple test case? Thanks!

I think the original report was correct and the issue should most likely be fixed in master with https://cgit.freedesktop.org/mesa/mesa/commit/?id=73df16dcee79e2281c8d8a830dbbe6655359c82d
