No, cleaning up cloud print code does not make print preview render different.

Note:Re-bisected and got the same bisect range mentioned in the issue, so removing Needs Bisect label as of now.

Thank You.

[Bulk Edit]- Assigning to In house-HYD Team and apply label - hasbisect-per-revison

If the issue still persist, try bisecting again with per-revision bisect script.

re comment #3 - this is not likely a dupe of 632274 - that was a MacOS specific issue with core animation, this happens on multiple platforms (and looks a bit different).
Labels: -M-53 -Needs-Bisect M-55
Tested this issue on Windows-10 High Dpi using chrome latest canary #55.0.2867.0 by following steps mentioned in the original comment.

Performed per-rev bisect using new script on windows and got the below Change Log with multiple suspects.

Unable to find actual suspect from the above log, Could anyone please look in to it and assign to the concerned Dev person.

Thanks!

I can reproduce the issue on Linux without using print preview at all. Once the attach photo dialog opens, zoom to 110% and the problem occurs on the website itself.

I went back to r360000 and I still see display artifacts around the "Drag a photo here" image when zooming in and out. Removing printing label since it happens even without print preview. Removing regression label since it happens with older builds too, though the exact display artifact can vary.

I would bet that this is due to background image using a sprite map. If so, it's a dupe and I'll mark as such.
Status: WontFix (was: Assigned)
For whatever reason this no longer repros, so maybe a dupe of the background image sprite map issues.
