Avif encoder produces artifacts when SharpModifier::class is used

[deluxetom]

Describe the bug

After using the SharpModifier, if I encode the image to avif, it produces artifacts.
The output looks correct with other modifiers, only this one seems to cause issues.

Code Example

use Intervention\Image\Drivers\Vips\Driver as VipsDriver;
use Intervention\Image\ImageManager;

$image = ImageManager::withDriver(VipsDriver::class)
    ->read('trim.png')
    ->sharpen(5)
    ->toAvif();

Expected behavior

Image should match other encoders:

Images

Current output in avif:

Environment:

• PHP Version: 8.1
• OS: Ubuntu
• Intervention Image Version: 3.11.0
• php-vips Version: develop
• libvips Version: 8.16.0

I tried using the sharpen vips method but I'm seeing artifacts as well, not as bad as the current method tho.

$image->core()->setNative(
    // $native->conv($this->getUnsharpMask())
    $native->sharpen(['sigma' => $this->amount])
);
