Graphic Glitches

I am getting slight graphical glitches after installing Leopard. They appear at random and quickly correct themselves but they are definitely there. It seems to occur most when using the scroll wheel. Anyone else experiencing this? My Mac Pro has the ATI Radeon X1900 graphics card.

Mac Pro 2.66 3 GB Ram, Mac OS X (10.5), 23" Apple HD Cinema Display

I have this problem on my mac pro (2.66) with x1900 running latest firmware. I get one or a few horizontal lines across the width of a window - if i move the window, the glitch moves with it, and if i activate the screen saver and go back to the window, it's gone.

it may be an unrelated issue, but i set final cut to use a different 'space' and when i went back to the main desktop, the title-safe viewer overlay came with it.

there seeems to be some problem with core image and x1900s?

Hello Everybody:

An issue with ATI's 9600 pro, Mac & PC video card:

I fresh-installed Leopard on my G5 Dual 2.0 GHz equipped with a 256Mb ATI Radeon 9600pro Mac & PC Card. --> I get video artifacts when moving an open window --> They dissappear after further movement of the window, but re-appear when moving text line-by-line using the arrow-keys and /or scroll-wheel.
The card must have a driver provided right within Leopard, since the card displays the Finder in "colour", not like in Tiger where it is Black & White when loaded without the driver provided by ATI - ATI provides a driver for Tiger, but not (yet?) for Leopard. --> Installing the Tiger drivers from ATI results in an "Unsupported Extension" error message from Leopard.
Only one resolution is showing in the Display Preferences.
It is odd that Apple includes a somewhat working driver for this card, but that driver does not fully support it.. any ideas?

Avoid APE extensions!!! when installing Leopard.

In regards to my earlier post about the 9600pro graphics card glitches under Leopard:

I did install the Tiger ATI 10.3.6 driver for the ATI 9600pro Mac & PC card successfully.
Upon restart, the resolution selection under System Preferences/Display was fully enabled and selectable. The ATI Displays extension 4.5.7 is incompatible with Leopard, that was the error message displayed. The artifacts did disappear!

I too have these horizontal glitches. I first noticed them in Mail... but later it happened in iTunes.

I swear, this ATI X1900 is a love-hate relationship! I love the performance but HATE the problems I've had with it. Ironically, I have an appointment to get the card replaced at the Apple Store on Sunday due to artifacts that started a couple months ago. The video card has bad RAM or something.

I have exactly the same problems regarding graphics in Leopard. Was on the phone with support for 3 hours trying to resolve the problem but no luck. Running a Mac Pro quad core 3ghz, radeon x1900xt with the Oct 16 firmware, and two dell 24 inch monitors at 1920x1200. System wide graphics don't render correctly. I mostly see horizontal lines that span across program windows, not screen wide. Also, graphics in the top left of windows are sometimes incorrectly drawn, with incorrect gradients and small lines cutting through the traffic light circles. Screen captures include the errors, so a hardware problem with the displays/cables isn't likely. Tiger ran perfectly on this system.

Originally clean installed Leopard and now doing it again. Will post if any improvement seen, although doubtful because I'm not the only one. I took photographs of each recurrence of the problem (at least 5 so far).
