Camera problems when changing between fullscreen and windowed modes

When changing between fullscreen and windowed modes on my Thinkpad, I'm being placed in the camera position for gameplay in the Sphere, but I'm still in the settings menu. Pressing escape to exit back into the game, and once more to return to the menu, fixes the problem. This happens when going into fullscreen, or when going into windowed mode.

I've attached a screen recording and a logfile.
