Video artifacts with ATI proprietary driver

[lingenfr]

I posted over at the ubuntu forums as they were already discussing the topic. I am getting artifacts using the newest ati driver. If anyone has experienced and then solved this, please post.

AMD 8.42.3 Driver Released -- The Baby Is Born!

Some of the examples that seem widespread include:
Slow scrolling, esp. in Firefox.
Slow FPS of compiz effects (maximize/minimize, cube rotate, etc.)
Corruption/screen artifacts over time, esp. surrounding the cursor

I'm running Ubuntu 7.10 64-bit with a Sapphire X1650XT card, 256 MB RAM on card. OpenGL screensavers with 8.42.3 have artifacts along the bottom half of the screen. Wolfenstein Enemy Territory (not Quake Wars) still runs but like 8.41, the brightness control does not change the brightness at all. Still tearing with AVI or most other videos. The only improvements I've noticed is that AIGLX works, and HD videos play much better, neither of which have any compelling use to me.

I'm going back to 8.40.4, it simply works better for my needs.

and AMD fglrx 8.42.3 - When will the baby mature ? - Experiences ..

Regarding the LR corner (and mouse) corruption i had that too. As i was told by another user on this forum: make sure you have these lines in your /etc/X11/xorg.conf:

Option "HWCursor" "On"
Option "XAANoOffscreenPixmaps" "true"
Option "RenderAccel" "true"
Option "AllowGLXWithComposite" "true"
Option "OpenGLOverlay" "off"
Option "VideoOverlay" "on"
Option "CapabilitiesEx" "0x00000000"
Option "no_accel" "no"
Option "mtrr" "off"
Option "KernelModuleParm" "locked-userpages=0"
Option "BlockSignalsOnLock" "on"
Option "UseFastTLS" "0"

Well - 8.43 is coming soon... (and then 8.44... )
