I think you may add this bug into the OP:
https://bugzilla.mozilla.org/show_bug.cgi?id=792639
I can reproduce it with every catalyst release, and a lot of users confirmed it in their 6xxx and 7xxx cards too.
I reported it at least three times using their contact forms (12.8, 12.10, 12.11)...
Can you provide more info (i.e. your Catalyst driver / Windows version / your browser name / hardware acceleration enabled or not / a screen with your temps / potential errors in event log)?
I discovered that this bug is caused by atioglxx.dll related to 11.8/11.9 driver versions. A workaround is to place atioglxx.dll from Catalyst 11.7 into the same folder of the program with an opengl issue (caused by 11.8 or 11.9 drivers).
So this bug is part of "OpenGL Extension Limit" issues...
An exception is thrown when an wglCreateContext is called when OPENGL32.DLL is dynamically loaded (using dynamic DLL linking). AIDA64 corrected this issue in latest beta using static linking of OPENGL32.DLL. Probably we should send this thread to AMD, because the reference in OP doesn't clarify...
Wonderful, I just note that AMD fixed many bugs in this version (not noted in official release notes).
I'm almost sorry to report you other bugs to evaluate/add... take your time. ;)
@Unknown-One: Please update your OP to reflect these info.
1) Existent bugs to update:
wglCreateContext Exception = NOT FIXED in 11.9 (as stated here)
DCOM Error = FIXED in 11.9, as stated in release notes.
I haven't verified other bugs in the OP, because I don't use CCC. Any other help would...
DCOM error seems fixed in 11.10 preview, but I'm waiting to try 11.9 final drivers for a definitive sentence.
Thank you Unknown-one. I admire constantly your efforts, providing us a direct channel with AMD.
I'd suggest to all followers of this thread to help in the research of any relevant bug...
