[Bug 125970] Re: slow scroll with image as background-repeat

[Cory Dodt]

I can confirm the bug, and I can confirm Mathias Buren's workaround,
posted 2008-08-19: upgrade Nvidia driver and add performance tweak to
xorg.conf.  With two caveats.

I installed the newest nvidia beta driver successfully, and followed
this thread http://www.nvnews.net/vbulletin/showthread.php?t=118088 to
set up initial pixmap placement.

Caveat #1: adding that command to .xinitrc didn't seem to work, I had to
run it from the command line.  I'm not 100% sure .xinitrc is being run.

Caveat #2: the improvement, while marked, is not a complete fix for this
bug.  Two sites I used to compare:

  1) Slashdot, jump into the comment threads and scroll.  The fixed control box on the left causes a noticeable slowdown normally.  With this bug, slashdot comments are tolerable again.
  2) http://www.bnrmetal.com/v2/search.php?name=black+sabbath is a site posted to mozilla bug 201307 as a test case for that bug.  It speeds up considerably, but is still extremely slow.
