I have a dedicated pc which is running on OpenEmbedded operating system and I am developing an application on this system. The pc has a AMD Radeon 7000 series graphics card on and it hooked up 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: enter link description here )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:

Section "ServerLayout"
Identifier "amdcccle Layout"
Screen 0 "amdcccle-Screen[0]-0" 0 0
Screen 1 "amdcccle-Screen[0]-1" 0 0

SubSection "Display"

EndSection

EndSubSection

I have already tried running

aticonfig --sync-vsync

Eventually it adds the following line to xorg.conf

Option "Capabilities" "0x00000800"

I killed the X Server after this change but the problem still persists.

According to me, the screen tearing effect shows up as a line but in my case it is like a Z shape. Can it be related to something else? Do you think that this is still called as screen tearing?

I'd appreciate your helps.
