I created a small (but perhaps not small enough?) example to illustrate the problem:
See: https://github.com/dov/QtGLProb Please test it under the following conditions to see the problem: 1. "qmake-qt4; make; ./debug/ModelViewer" 2. "make clean; qmake-qt5; make; ./debug/ModelViewer" 3. "env vblank_mode=0 ./debug/ModelViewer" Case 3 eliminates the problem for small window sizes, but when enlarging the window to the full screen, the same lagging behaviour as in case 2 is experienced.
