In the standalone engine only, if I apply a border, a mask, or a crop, the moment I release a slider or hit return after entering a value, the display for all layers disappears, leaving me looking at a checkerboard with some interactors and a bounding box showing where the image should be.
The display only reappears when I return values to "0"
Ideas? Everything works fine from within Premiere.
It might be that you are have OpenGL enabled and other resources on the system are vying for control of the board. What happens if you disable OpenGL preview in RED ... do you see the same result as you reported? What are the specs of the system on which you are running RED and experiencing these symptoms?
