                    left at startup
           Product: xorg
           Version: 7.1
          Platform: x86-64 (AMD64)
               URL: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=178

I've been seeing this (minor) bug for over a year. Please look at the
bugzilla.redhat.com report linked for some more details.

It's still happening with XOrg 7.1.

Quick description of the problem : A vertical bar of a few pixels appears on
the left side of the display and contains what appears to be an horizontal
repetition of a 1 pixel wide vertical stripe from what is missing on the right
side of the display (the display is like "moved" to the right, and "wraps
around" in an odd way).

When does it happen?
- When I boot the computer with the TV turned on

When does it not happen?
- When I boot the computer with the TV turned off
- When I boot the computer out of "hibernate" (swsusp, "suspend to disk"), even
with the TV on
- When I switch to any text VT then back to X, it goes away (see the video)
- When I use the vesa driver instead of the radeon one

Hardware and software :
- Shuttle AMD 64bit barebone
- Asus AGP Radeon 9200 (not SE)
- BenQ 37" LCD TV connected through DVI, at max resolution of 1280x1024
- Fedora Core development x86_64 fully updated (XOrg as recent as it gets)

I've always suspected something to do with the TV's dimension, as it's BIG
(it's the TV from bug #6004)...
