          Priority: medium
            Bug ID: 82533
          Assignee: dri-devel@lists.freedesktop.org
           Summary: Line of tearing while playing games
          Severity: minor
    Classification: Unclassified
                OS: Linux (All)
          Reporter: dawide2211@gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: 10.2
         Component: Drivers/Gallium/r600
           Product: Mesa

Created attachment 104534
  --> https://bugs.freedesktop.org/attachment.cgi?id=104534&action=edit
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.

Glxinfo

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) &
fi

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.
