I recently upgraded from a working 11.2 to 11.3, using x86_64 for both, and it worked fine for the most part except my firefox is unbearably glitchy. What happens is that part of the display in the web viewer (though it has happened in the search bar as well) will go black, and it will stay black until there is a redraw event, i.e. until I scroll the window a bit or move the window around. I can’t take a screenshot of it, it always looks fine (but I promise I’m not going crazy!).
Anyway, I have often had a minor struggle with my ati 2400 pro, it is currently working fine, I just checked the 3d acceleration and it is definitely rocking. But basically what I did (though there have been more steps now but these are the ones I think worked) is I installed the ATI driver with the one-click install, and then I ran “aticonfig --initial” as root from the command line. I’m not so sure whether that helps or not.
The problem persists when firefox is run in KDE, and I think I may have seen screen glitches here and there, just not to such a usability breaking degree.
Unfortunately I’ve been really busy lately, and I am going to a movie tomorrow after work, so I am having a hard time getting enough time in front of this to try to fix it, but I would definitely appreciate any help I can get. Let me know if you need to know more info about my system, I will certainly respond as soon as I can.
Oh wait I don’t know if this is significant but to get the black to refresh I have to scroll it out view–i.e. the black will scroll up and down as if it was the image until it goes out of view. I guess I mean I don’t know how that is significant–it seems to put the bug somewhere in how the images are being stored by either the video card or X windows, right? I guess I have no idea what could cause that either.
Thanks again, I think I’m going to go watch some tv and then catch some sleep, enough aggravation for one night.

I believe I have tried it with the effects on with no change. My effects are generally off though, not in front of my screen now so I can’t double check that they don’t work with them on. Will try that later.
You pick out KDE in a comment. Does that mean you normally use Gnome?
Some settings to check in KDE System Settings:
In the Default Applications > Window Manager: Make sure it’s set to kde’s kwin window manager and not compiz
Desktop Effects should be OFF
Logout and back in after making the changes (if any)
Ok great, I will give that a try when I get home. I do have a different login screen, haven’t tried changing that (I just used the other one to log into a KDE session.)
My settings match that in the gnome screen shots. I do not have effects enabled. Should I try to switch login managers or was that just a misconception on my part?
I can’t post a shot of firefox that shows the problem using the printscreen utility. I could take a picture with my camera, but I don’t have that set up to work quite yet.
Driver: "fglrx_pci"
Driver Modules: "fglrx"

Driver Info #1:
3d acceleration definitely is on,
glxinfo | grep direct
returns
direct rendering: Yes
and
glxgears
gives me
18271 frames in 5.0 seconds = 3654.030 FPS
18337 frames in 5.0 seconds = 3667.261 FPS
But believe it or not chrome seems to be working fine! Of course I would still like to get this fixed but with this realization the priority for me is a quite a bit less.
