Description
When running the lighting example with the OpenGL 2 graphics system, the performance is significantly worse than when using the raster or OpenGL 1 graphics systems. Furthermore, the performance degrades for each additional lighting example run concurrently with the OpenGL 2 engine.
Reproduced with Qt 4.6 branch on Windows Vista (SHA-1: f6dee67827e72a0660f37998dafb18c6ccd9834e) and Linux.
