Rendering is performed using WebRTC class. Additional logging did not reveal the problem - everything seems to work fine, however no image rendering on the window. I've made a 200ms delay after rendering initialization as it seems that with such delay bug does not reproduce.

Figured out the problem - OpenGL canvas was rendering on a window which (sometimes) was not displayed on a screen upon creation. Fixed by forcing window to be displayed once created (http://stackoverflow.com/questions/15936059/how-do-i-detect-invalid-drawable-in-mac-os-x).
