Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.59 Safari/537.36 Steps to reproduce the problem: 1. Open index.html (see attached zip file). 2. Press ctrl+a to select all text. 3. Click text by right mouse button and select "Print..." 4. Text of last paragraph will be overlapped by "empty" image. What is the expected behavior? Text on preview page should not be overlapped by images. What went wrong? Seems like Chrome uses different modes for Print of selected text and print of whole page. In first case not all @media print CSS rules works. When you change options on preview page (check/uncheck Background graphics or check/uncheck Selection only) preview PDF becomes different. Did this work before? N/A Does this work in other browsers? Yes Chrome version: 54.0.2840.59 Channel: stable OS Version: 10.0 Flash Version: Shockwave Flash 23.0 r0

Looks like it's due to the line "m_cachedImage = StyleInvalidImage::create(url());" in CSSImageValue.

Created minimal test case: https://jsfiddle.net/swxckne3/ <!DOCTYPE html> <style> #target { position: absolute; width: 100px; height: 100px; background: url("filesystem://"); } </style> <div id="target"></div> Open print preview, the text on this page should not be cut off at the start. https://codereview.chromium.org/1865603004 caused us to store computed FillLayer image values even if they can't be resolved to an image resource. Instead of nullptr we store StyleInvalidImages. Seems like something is seeing a non-null value for the background FillLayer and attempts to paint it but only in print preview for some reason.

nainar: Would you be willing to investigate this one from here? I think I wouldn't benefit as much from digging into print code as you would.

This is not something we can fix on the printing side. Blink is painting the contents. Adding the Blink>Paint component for triaging.
