Hello,

i just installed opencv3.3 under vs2017, windows 8.1, and tried imshow, which was runnin perfect under 3.2.

the result is a grey picture and the window state is: no response. i tried it with 2 different cams and with precompiled 3.3 as well as self compiled 3.3, same result.

image description

VideoCapture cap; if (!cap.open(1)) return 0; for (;;) { Mat frame;

        cap >> frame;
        //cap.read(frame);
        //cap.retrieve(frame, 1);
    if (frame.empty()) break; // end of video stream

        //frame.AUTO_STEP;
        cv::imshow("RoboCam", frame);
    }

the debugger steps permanent through the for loop while showing the window

do you have any ideas or same results with 3.3 ?

many thanks for your help !
