Well, 12.6 is slightly outdated, don't you think ? What about the fresh 13.1? If you agree to download it, then please go there (http://support.amd.com/US/GPUDOWNLOAD/Pages/index.aspx) and select steps from 1 to 5. In your case, it'd be:
Step 1: Notebook Graphics
Step 2: Radeon HD Series
Step 3: Mobility Radeon HD 4xxx Series
Step 4: <Your Windows version>
After this, click at the "Step 5", and you'll see the download page. Good luck .
FYI on 18th Jan. the driver wasn't updated. Update was released on 21st Jan. Anyway Thanks.
Let me see if it solve my problem.
Thanks, really appreciate it.
I had similar troubles recently and it took me a while to figure out what's wrong and how to fix it. Morphological filtering is the culprit.
