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

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