• Resolved visible corruption when starting MythTV frontend in full screen
• Catalyst Control Center, disabling primary display and re-launching CCC caused a Floating Point Exception
• Google Earth failed to start
• With some ATI adapters the display port monitor was not detected after being hotplugged
• Able to reboot or shutdown when ATI Catalyst Control Center is opened
• Catalyst Control Center, displayed the wrong version using the Information/ Driver Version
• No audio output was available through HDMI
• Connecting both a CRT and DFP display device no longer results in the CRT failing to display an image if the DFP is disconnected and then reconnected to the system
• Corruption is no longer seen on secondary display after enabling secondary display Big Desktop
• Sections of the task bar no longer turn black when using the application 'Blender'
• Enemy Territory Quake Wars v1.4, system no longer becomes intermittently unresponsive when game is run.
• Some Open GL application no longer cause segmentation fault with Crossfire and dual head enabled
• Maya crash fixed when using the following settings subinvisions Axis and subinvisions Height are set to 2000
• Tearing no longer occurs during picture-in-picture playback of H.264,VC-1,MPEG2 files on SUSE
• Playing AVI files with Mplayer in full screen no longer causes Mplayer to stop responding
• Resolved, Video does not resize or may appear filled with pink/black when changing from a low to high resolution

• White screens may occur on the extended displays of a with a quad display configuration with 'Xinerama=on'
• Quake4 cannot start after using the load default option
• With both a DFP and CRT connected using the swap monitor option may cause the following error “KDE Panel - The KDE Crash Handler”
• X may fail to start when the driver has been configured with the following command: aticonfig --force-monitor=nocrt1
• RedHat 4.7 hot plugging a display may cause X to shutdown
• Some display corruption may be observed while returning from XServer with two display connected
• Catalyst Control Center, primary display manager may be missing on systems with dual head enabled
• Some systems may fail to restore after returning from hibernation
• Catalyst Control Center, the primary display is not identified when using the Identify Displays button
• X-Server may become unresponsive when hot plugging the display after changing the resolution
• Dual head mode, the mouse cursor cannot move to the secondary displays
• The mouse cursor may fail to render when hot plugging a display in clone mode
• Catalyst Control Center, on some systems X may fails to start when the resolution is set to less than 1680x1050 through displays manager
• With some system configurations Catalyst Control Center may take up to 30 seconds to start
• SUSE 11, No CrossFire confirmation is displayed when running Open GL applications
• Running Specviewperf 9.0.3 in CrossFire mode may causes a segmentation fault and failures in log file.
• When X is killed, the desktop background for the display:0.1 remains
• Screensaver corruption may be observed with 'xinerama on' in multi-head configuration. On Novell's openSUSE, SLED and SLES operating systems running “sax2” or “sax2 -r” on the console overwrites the X.Org configuration file xorg.conf, reverting changes made by running “aticonfig --initial”. As a result subsequent X session may start up using the open source Radeon on X-Vesa graphics drivers instead of the proprietary ATI Linux Graphics Driver. Solution: Do not use Sax2 when the proprietary Linux Graphics Driver is installed. Instead configure all display parameters using the Catalyst Control Center--Linux Edition or the aticonfig command line interface.
