Is flatshading supposed to work when vertex color clamping has been deactivated with the following call?
glClampColorARB(GL_CLAMP_VERTEX_COLOR_ARB, GL_FALSE);
On nVIDIA cards (tested on Quadro FX 4400 & 4500) on Linux, flatshading seems to be deactivated when color clamping is deactivated. Is this the correct behavior? The specification doesn’t say anything about flatshading.
