Does it change the resolution or truncate the widget? Let's see if we can try something else. The only thing i found to change the webcam resolution is with OpenCV. Really horrible, because that's a huge library to load just for that, but it's worth trying.. Could you try the following script, changing the resolution? http://stackoverflow.com/questions/11420748/setting-camera-parameters-in-opencv-python Or, if you please, the following: #! /usr/bin/python # apt-get install python-opencv for this import cv2 # capture from camera at location 0 cap = cv2.VideoCapture(0) # try to change the width and height cap.set(3,800) cap.set(4,600) while True: ret, img = cap.read() cv2.imshow("input", img) key = cv2.waitKey(10) if key == 27: # escape quits break cv2.destroyAllWindows() cv2.VideoCapture(0).release() If this makes the window smaller and less laggy, maybe I can try to factor this into monkeysign...
