Recently, I reinstall my computer, and now, my very simple GLSL shader give me strange flickering artefacts with many small coloured squares . Those artefacts are only visible on geometries.
Windows 7 64bits, Nvidia (Asus) GTX 550 Ti
If I remove my shader binding and only use fixed pipeline, I have no artefacts at all.
It seems that coloured squares always have the same rectangular size (3 x 6 pixels)
What is the common cause of this kind of artefacts ? Could it be a problem with Uniforms settings ?
I changed nothing in my shaders and it was working before my computer reinstall.
