Could you share a apitrace recorded with radeon?

$ apitrace trace gst-launch-1.0 gltestsrc num-buffers=100 ! gltransformation !
glimagesink

Here you can find apitraces for intel, nvidia and nouveau:

The issue is reproducable with the recorded apitraces. I am able to run the
nouveau trace on intel with correct results.
I can reproduce the intel trace bug on nouveau.

$ apitrace replay gltransformation-nouveau.trace

This should also show the test src for you.

I wonder why it does work on nouveau, since it shares the same Gallium backend
as radeon.
