AMD Catalyst Driver Version, and Driver History
Current driver: 12.8

Previous driver: 12.6

Operating System

Issue Details
Sound panel issue:

When trying to open the Windows sound control panel, nothing happens. After a while, the sound control panel does pop up, with the right tab open. The computer remains otherwise responsive. It's more of a "opening with delay" than "opening because things are running slow" situation. Driver version 12.6 did not exhibit this problem.

Firefox issue:

While surfing with Firefox, after a while, the page being rendered turns black. Either mostly or completly. Scrolling down on the page does give glimpses of it, however it get covered in black again once scrolling stops (using smooth scrolling). After less than a minute once this happens, Firefox crashes. Driver version 12.6 did not exhibit this issue.

Additional Details

No hardware or software changes between 12.6 and 12.8. Issues appeared directly after reboot. Disabling Hardware Acceleration in Firefox seems to have solved the issue. Still happens with the 12.8 driver.

Hi

I have the same problem with Firefox. I see on another forum that the issue was to disable CrossFire (2 X 5870 for me).

For the moment, my Firefox doesn't crash.

But it isn't a definitive solve, I must use my crossfire by moment

Decided to roll back to 12.6. Had a complete system freeze while running a full screen 3D application (The Witcher 2), and another while running Firefox. Neither one seemed to be a bluescreen, the screen just froze (might just be because it's the display driver crashing).

If someone has found any alternative solutions though, I'd love to hear them. I was hoping to take advantage of the performance improvements documented in the 12.7 release notes, however I experienced these same problems while using it.

Alternative/best solution:

1. Check you RAM for errors (memtest86)

2. Check your CPU stability (prime95)

3. If both go well, do a fresh OS install. If you don't want to wipe your system just to try it, install into a separate partition or make a backup first.

I have the FF issue.  It crashes constantly but I found the workaround.

Running 12.8 64 bit windows 7

crossfire and multi monitor

FF are 14 and 15 both.

Tools-->Options-->Advanced-->General--> Uncheck Use hardware acceleration when available

No more crashes and I can't tell a performance difference.

This is based on Mozilla's doc on troubleshooting.  They speciffically say, if there are no crashes in safe mode, but crashes in non-safe mode with ALL plugins and extensions manually disabled then the graphics driver may be at fault and to disable acceleration.
