Hello.
I am having trouble when mixing rgba- and depth textures in the same shader. If a shader reads two depth texures then things work fine, but if I change one texture to rgba the depth texture stops working properly (the depth texture always return 1.0).
Platform is: Linux / FX 5700 / driver 61.11
The details are included below in a test application that is available via URL.
Please test it and report if it works for you - especially if you have a different system !!
