Hi,
i did something by accident and now i can not get rid of cursor in viewport set to rendered with cycles. It draws on top of the rendered view and i just can’t kill it.
Any help is welcome 
Properties panel (N), under Display enable ‘Only Render’
Ah, thanks. As far as i remember i never had to do anything to disable cursor in rendered viewport in versions prior to 2.74. I am not sure of it though…
