Mistake "crazy" with video playback

[deusr]

I have downloaded the sabayon9 and recorded on a flash drive to install on the notebook. I have Installed and is running normally "very well", taking some unexpected.

If I boot the USB stick and go see a movie, for example AVI, it will run very well. No catch nothing, It runs perfectly.

If I tryied to direct a film system, sabayon, installed on my notebook when there is change of scene or when the camera moves in the film, the image is cut, it seems that is delayed. I still can not identify what can be. Can anyone help me with this?

My machine is an Acer Ultrabook S3 core i7 with a second generation SSD and 4GB of RAM.

The problem is called "Screen tearing". The most strange that the system running the stick does not.

No one has no idea what could be?
