Turns out that compute shader is unable to sample from depth texture. The attached program first renders a shape to a FBO. Then a compute shader is used to copy the color and depth textures attached to the former FBO to a shader image, which is drawn to the screen. The depth part is different between nouveau and other drivers. Compile the program with gcc test.c -lglfw -lGLEW -lGL</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
