Wow - you, Sir, are good! I am really impressed.

After installing the package, I saw that the values are initialized at
R7 = 0, R8 = 2. Sharpness is initialized to 2.

As soon as I changed R7 to 1, it worked perfectly. This also yielded a
perfect image quality (at some settings there was weird noise patterns).

Also when I raised the sharpness to the max level of 3, the bug appeared
again.

So thank you again for your solution and my kudos again. Awesome! Also,
svv is a really neat tool, I'll surely use that in the future.

Best regards,
Joe
