apitrace of scene

I have attached an apitrace of the scene in question.

The apitrace plays back normally in Windows, and using the llvmpipe driver in Mesa. However, in VMware, the scene is "garbled", everything looks wrong.

I actually took the apitrace capture using the VMware driver, where it looked wrong, and when I play it back anywhere else, it looks normal.

I should point out, we've had one other user report this issue on a different GPU, and it happens on Android as well, but no other desktop drivers.

I figured out the issue, our application is reading/writing texels in shaders without setting proper barriers in place. It is a bug in the application, not the driver
