are you rendering with opengl on (in the render settings, is use opengl enabled)? and is opengl for previews set to 'always on'?
if so, try setting the previews to use opengl-interactions or to use adaptive resolution only, and set your render settings to not use opengl... i would rarely recommend setting final renders to use opengl, and i would only sparingly set opengl for previews to 'always on', opengl is just to flakey.
Your layer handles (as seen in the screenshots) look like a clue, though, since they coincide with the edge of visibility at Full Res. Can you try hiding the layer that you've selected in the screenshots?
