For the attached 848x480 stereo input, SDE vision_apps demo produces artifacts in  the left border of output disparity map on EVM. (See Fig.1).  The output disparity map on PC is fine. (See Fig.2). This is not a visualization issue. The binary output from SDE node for the same input are different on EVM and PC.
