Temporarily workaround regression with NVIDIA.

Browse source 
KWin's new shaders fail with NVIDIA and present just a black screen
for the ortho shader (generic shader seems to work). Temporarily
disabling the shaders to force a fallback to old rendering code.

Of course the bug in the shader needs to be fixed.
