I have observed this bug both with Intel (Iris Pro 5200) and AMD (Radeon R7 370) GPUs. It doesn't only happen with deprecated variables, but also when using a OpenGL core (3.2) context and corresponding shaders, by adding "invariant gl_Position;" to a vertex shader (doesn't seem to affect all vertex shaders, though). It can be reproduced with this branch of Yamagi Quake2: <a href="https://github.com/DanielGibson/yquake2/tree/mesa-100316">https://github.com/DanielGibson/yquake2/tree/mesa-100316</a> (start with ./quake2 +set vid_renderer gl3) The corresponding source is: <a href="https://github.com/DanielGibson/yquake2/blob/mesa-100316/src/client/refresh/gl3/gl3_shaders.c#L328-L329">https://github.com/DanielGibson/yquake2/blob/mesa-100316/src/client/refresh/gl3/gl3_shaders.c#L328-L329</a> (<a href="https://github.com/DanielGibson/yquake2/blob/mesa-100316/src/client/refresh/gl3/gl3_shaders.c#L261-L288">https://github.com/DanielGibson/yquake2/blob/mesa-100316/src/client/refresh/gl3/gl3_shaders.c#L261-L288</a> is also part of the shader) When adding "invariant gl_Position;" into my simpler vertexSrc2D shader (<a href="https://github.com/DanielGibson/yquake2/blob/mesa-100316/src/client/refresh/gl3/gl3_shaders.c#L166">https://github.com/DanielGibson/yquake2/blob/mesa-100316/src/client/refresh/gl3/gl3_shaders.c#L166</a>), it does not create an error there. As Olivier wrote, compiling the shader gives no errors, but linking the vertex- and fragment-shaders into a program fails. The error message doesn't even mention gl_Position directly, but some other variable (in my case "error: declarations for uniform `transModel' have mismatching invariant qualifiers") - but when commenting the "invariant gl_Position;" line out, it works.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
