Qml application strange behavior on nvidia card enabled

I am using Ubuntu 14.04 with two graphics card - first from Intel and the second one is NVIDIA Corporation GF108M [GeForce GT 635M]. On Intel card every qml applications works well, but on nvidia card, even the simplest qml, not. When I am resizing window, the window content "flows" faster than window is resizing and disappears outside window frame leaving artifacts. Just watch this video. To enable nvidia card I am using optirun from bumblebee package.
