Attached is a PNG screenshot of what we see when loading the Print UI -- notice how corrupted the QR code is compared to the source PDF doc We have many customers in the field that use the Chrome PDF viewer to print PDFs containing 2D barcodes so this is particularly problematic Chrome Version 57.0.2987.133 on Windows 10

Did this used to work, but is broken now? If so, do you remember about when it last worked correctly?

Yes, it definitely worked fine up until recently. We started receiving reports about this problem on March 14 so it started some time shortly before that. All of our customers are on the Stable channel so hopefully that narrows down roughly what version introduced the breaking change.

I can reproduce the issue in comment 6 - after scrolling in the print preview I see the distorted QR codes (they seem to load okay initially). Can also reproduce in the Chrome PDF viewer outside of print preview by zooming in a bit and then scrolling. Despite the bad preview, this seemed to print correctly when I tried it. Does this affect printouts as well or only the preview? Also, I can't reproduce the issue in the original report, so comment 6 may be a separate problem.

Yes, we have people both with thermal ticket printers and classic laser printers (both exposed as standard Printers in Windows) and have agreed that printed output also has the black lines. There is one wrinkle -- it has to do with the number of images in the PDF. We've heard reports that with only a single image, the black lines appear in preview but not on the printed output. But in all cases, with more than 1 image, the printed output has the black lines

dave@, can you pls file a separate bug since yours is a different problem from OP's. Yours happens not only on Windows, but also on Mac and Linux. xerpres@, can you pls confirm that your problem only started showing up recently? Do you remember roughly when?

xerpres@, can you pls update Chrome to version 58 and check? Looks like the regression is fixed already.
