Issue description
UserAgent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/66.0.3359.139 Safari/537.36
Steps to reproduce the problem:
1. Apply a CSS filter on an image
2. Print with these arguments:
{
landscape: true,
displayHeaderFooter: false,
printBackground: true,
scale: 1,
paperHeight: 6,
paperWidth: 4,
marginTop: 0,
marginLeft: 0,
marginRight: 0,
marginBottom: 0,
pageRanges: '', // all pages
preferCSSPageSize: true
}
3. Notice that the image quality appears visibly downgraded.
What is the expected behavior?
Image quality should not suffer when adding a CSS filter.
What went wrong?
Note the image without the filter appears high-resolution. The filter (any CSS filter) appears to impact the image qualty.
