<div dir="ltr">Thomas,<div><br></div><div style>OK, thanks for the update. I don't have a working machine with NV graphics that supports UBOs. Could you compile and run a test program for me if I wrote it? Though it may appear to not work for UBO offsets other than 0, there may be another pattern here, such as multiple of page size or something crazy like that. If we can find more information, it may help other developers.</div>

The problem only appears when using an offset that's not zero.If you want to debug the issue you could very well use the dolphin-emu and <span>apitrace</span>.<br></div>You can find one <span>apitrace</span> here http://<span>markus</span>.members.<span>selfnet</span>.<span>de</span>/dolphin/dolphin-emu.trace (~48M)<br>

If so, can you write a test case for it that shows the problem? If not, would you mind running a test case if I wrote it and letting me know how well it works (if at all)? I'm not a nouveau developer, but I do have an interest in seeing this bug resolved (my app needs working GL 3.3 support) and I imagine compiling and running an emulator (including downloading test ISOs) is a very... un-fun ... task to reproduce your bug, indeed.</div>

<div dir="ltr"><p dir="ltr">Oh and just for the sake of completeness the problem occurs in the form of wrongly rendered textures in front of a black screen. The objects only are fusible for a second and them disappear sometimes they appear at the wrong position or are rotated.<br>
If you compile dolphin with GLEW_ARB_uniform_buffer_object replaced with false in Source/Plugins/Plugin_VideoOGL/Src/Render.cpp the problems won't occur.<br>
