Hi there,

I found a strange problem today after connecting my new monitor to my computer.
With the new monitor I am using a multi monitor setup of size 3200 x 1080. But
it seems some applications are having troubles displaying anything beyond the
apparently magical line of the (virtual) x-coord 2640.
The troublemakers so far are:

- GVim
which renders no text beyond the magical line. This happens mid-character.
vim in a terminal behaves fine.

- Tint2
which shows no application icons in the system tray after 2640. Also happens
mid-icon. The clock has no problems. The rendering of icons in xfce4-panel
works strangely.

- MPlayer,MPlayer2, VLC, Skype
those freeze, but only in the "danger zone"; so they play a partially
frozen video

- xterm
same problem as with GVim. Other terminals (rxvt, Roxterm) are fine.

- Conky
Same as Gvim and xterm

Most other applications are not affected by this bug.

This problem seems to be independent from the window manager, as it occurs in
openbox-multihead, vanilla openbox, i3, dwm and awesome.

I am enabling my multihead setup via xrandr:
xrandr --output VGA-0 --auto --pos 1280x0 --output LVDS --auto --pos 0x280

Package infos:
- xorg-server 1.12.3.901-1
- xorg-xrandr 1.3.5-1
- libxrandr 1.4.0-1
- libxinerama 1.1.2-1
- xf86-video-ati 1:6.14.6-1

Further information:
xrandr output: https://pzt.me/7o17
Xorg.0.log: https://pzt.me/9fb4

Here are some pictures. As you can see, the text gets cut mid-character, but
strangely, the textdecoration is not affected.

Is this an upstream bug?
This task depends upon

Follow up:

This bug doesn't happen if I configure the xserver statically
and use Xinerama.

Still a problem with latest xorg version?
If so please report to the freedesktop bugzilla.

So Alex Deucher told me that it's basically my graphic card being to wimpy to handle such a large surface.
