RX 480, mesa git, llvm 4.0.0svn_r290385 They have an OpenGL 4.1 and an OpenGL 4.5 backend and it happens on both. Here is a video with the 4.3 backend: https://www.youtu= be.com/watch?v=3DVpNFhlzsLHg Here is a (50 megabyte compressed) trace with the 4.5 backend: https://ha= agch.frickel.club/files/interface.trace.xz Possibly an application bug, but glretrace prints no real errors. If you want to run it yourself, you will need this fix: https://github.com/highfidelity/hifi/pull/9264#issuecomment-26894391= 7
This app looks like totally buggy. Rendering is broken with NVIDIA blob and Nouveau on Maxwell, on SKL and radeonsi. :)

Yup, trace does not even run with AMD blob also... likely does not work anywhere.
I think the correct status should be NOTOURBUG but whatever.

I've reopened, but feel free to close again if it still doesn'= t work on other drivers. Now that it doesn't hang my GPU anymore I've spent a couple of hours tweaki= ng the source code, available here: https://gi= thub.com/ChristophHaag/hifi/commits/master The rendering is better now: The blocky stuff is not green anymore, but it = did not disappear. New video showing the problem: https://www.youtu= be.com/watch?v=3Dpda7cNx3ATE And here is a new trace that runs with an actual 4.5 core context with no m= esa GL errors anymore: https://haagch.frickel.club/files/interface-blockartifacts.trace.xz (512 mb uncompressed) If you want to run this trace right now, you need the patch from bug 102308, currently on the list https://lists.freedesktop.org/archives/mesa-dev/2017-August/166827= .html
Tried it on nouveau, but I get a ton of Mesa: User error: GL_INVALID_VALUE in glBindBufferRange(offset misaligned 704/256) This is due to the alignment requirements for constant (and texture) buffers being higher on NVIDIA hw than AMD hw.

It doesn't happen anymore on HiFi's RELEASE-7150 tag and radeo= nsi git, so either of them probably fixed it in the meantime. I'm very happy to close this again.
