Hi all,

I have a dedicated pc which is running on OpenEmbedded operating system. I am developing an application on this system. The pc has a AMD Radeon 7000 series graphics card on and it connected to a full HD DELL monitor. When I show a video (about 25 fps.) I see the screen tearing effect on the screen. The effect is more visible if the fps. increases. I captured a video where you can clearly see the effect. The tearing occurs mostly on the right side of the monitor with a vertical Z shape. (Video link: https://www.dropbox.com/s/1mozdalh7tq7et7/screen_tearing_issue.mp4)I haven't got any clue why this is happening. Could you please tell me possible reasons that I can try out?

Here is the xorg.conf file:

If you need help from AMD why not turn to AMD instead? This is a user to user forum, not AMD support.
