    Description

      Since change 6155050f, Qt is having problems compiling its OpenGL shaders on my laptop with an NVidia Quadro FX 880M/PCI/SSE2, using driver version 260.19.06. I can't tell anymore whether it also happened with previous driver (which doesn't seem to work anymore with my current kernel).

      See attached examples of shader compilation errors. The qmlviewer only manages to display some black or white rectangles.

      Also attached is the output from glxinfo.
