--- Comment #3 from gregory.hain...@gmail.com --- I have the same issue on my application (PCSX2). The code in link_varyings.cpp (varying_matches::record) is potentially wrong but it isn't the main issue. I try to comment the code and the issue is still here. Nevertheless the code feels wrong as you don't know the existence of the consumer in SSO. So the flat optimization is likely bad. Anyway I try also to render the texture coordinate in the screen. Normally they must be interpolated between [0;1] however the interpolation is done between [-1;1] (potentially with a different sign). Indeed applying a rescaling of the coordinate in the FS, (t + 1.0) / 2.0 seems to render correctly my draw call. It seems [-1;1] is a default value of the raster unit. The behavior is the same if the texture coordinate is not written in the vertex shader. Maybe the code is optimized in the VS. Unfortunately I don't know if there is any possibility to dump VS asm code with Nouveau. -- You are receiving this mail because: You are the assignee for the bug.
