opengl shader uniforms are not updated with every primative (bug?)

[idata]

gl ver=3.3.0 - Build 8.15.10.2712 ven=Intel

I'm having some issue with my graphics code when run on intel i7 hd4000 integrated gpu. no issues with radeon or nvidia gpu. I have a glsl shader which is executed on a list of quads. Before rendering each quad I set a uniform variable (type 4f) For the first quad uniform variables are sent fine, however in the following invocations, the uniform values don't get updated. Is that a know issue with the intel driver?
