motion blue and black image on built in server - saved images are ok

I'm experimenting motion on my desktop, My webcam: Logitech, Inc. Webcam C270 Output Images and video are ok but the image on built in server aren't. They are like blue and black - almost monochromatic but sometimes it get gray also. I've tried open with vlc and it's ok - I think it's related with the video compression before transmit it to the server.
