Hello,

I have QGraphicsView and OpenGL scene with 1 item. My painting doesn't take much time (about 1-2 msec), but whole paintEvent time takes inadequate long (150-200 msec).

The problem exists not in all software/hardware configurations.

What can be the reason for this?

Thank you!

The reason can be incorrect code.
