QOpenGLWidget on Mac OS X
-
Do you faced with performance problem using QOpenGLWidget on Mac OS X?
I have a problem when one window has QOpenGLWidget and other widgets, QLabel, for example.
If QLabel updates text at ~30Hz then cpu loading rises to 50-60%, even if QOpenGLWidget doesn't updates and paints nothing.
If you replace QOpenGLWidget by QGLWidget, or open QOpenGLWidget in separate window , cpu loading is normal and about 20%.Am I only one who find this issue? And how to debug/profile this problem?
