Example 1, Unvanquished
While playing games with Vsync turned on a horizontal line of tear constantly shows up on the top side of my screen. This happens every time the screen moves and it means that it's pretty much always there.
With Vsync turned off it doesn't show. I tried the same games on my Windows partition and it doesn't happen there.
My monitor is an LG FLATRON W2453V, the video card is a Sapphire Radeon HD 6750 1GB GDDR5.
I'm using arch linux with kernel 3.15.8 and Mesa 10.2.5, the window manager is Openbox.

Please attach /var/log/Xorg.0.log and the output of dmesg and glxinfo.
Are you using a compositing manager? If so, make sure it unredirects fullscreen windows.

My current setup is: SLiM as login manager, Openbox as window manager, feh to show the desktop wallpaper, Xcompmgr for transparency, xfce4-panel for the panel.
My autostart for Openbox is like this:
feh --bg-scale /home/davide/Immagini/background.jpg &
if which xfce4-panel >/dev/null 2>&1; then
(sleep 2 && xcompmgr) &
(sleep 2 && xfce4-panel) &
I'm using linux 3.15.8, Mesa 10.2.5 and Xorg 1.16 on archlinux.

xcompmgr is a software compositing manager if im not mistaken. Try stopping it before starting your games.
The tearing is due to xcompmgr, please use a compositing manager which can unredirect fullscreen windows.
I'd suggest compton myself, I have no tearing when I tell games to limit themselves.
Compton fixed the tearing issue, thanks.
