Using a software OpenGL driver under OpenCL to bypass poor 3D performance and buggy 3D rendering of AMD GPU drivers.
I know this is a crazy idea, but could it make for more stable OpenGL rendering on AMD GPUs to use a software OpenGL driver running under OpenCL? Could it possibly even perform better? Thoughts?

it will be a lot shower but i think it will work

I bet the open source radeon drivers would be much faster. You see, GPUs have special parts designed for processing graphics. Just think about shader processors, the tesselator etc. Opencl can only use the GPU for calculations. Even if you write opencl code to compile shaders, it won't use the dedicated part of the GPU designed for this task.

Therefore, the proper way to solve the problems:

1. Make sure you report everything to AMD, so they know about issues people have. This is the first step required before anything can be fixed, and people barely do it. http://www.amd.com/linuxreport

2. If you happen to be a developer (many linux users happen to be), contribute to the development of the open source drivers. Probably it's even less of a hassle than rewriting opengl from scratch...
