Created attachment 8657616 [details] linear-gradient-zoom.html User Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0 Build ID: 20150905030205 Steps to reproduce: View attached testcase and zoom out the page. The background of the div is a linear gradient with a repeating 1px line. Actual results: The rendering of the linear gradient background is wrong. Interestingly the issue is visible on http://lea.verou.me/css3patterns/#blueprint-grid but not on http://lea.verou.me/css3patterns/#lined-paper .
Created attachment 8657921 [details] about-support-graphics.txt I have a Intel/AMD switchable graphics setup, and I can only reproduce the issue using the Intel graphics. I attached the graphics section of about:support. It looks like all HW acceleration is turned off for this configuration. With the other GPU, the behavior is the same as in Edge (the lines disappear).
Reproduced on latest nightly and devEdition. both of them renders correctly when the page is zoomed at 90%

Ever confirmed: true
Product: Firefox → Core
"Panning and Zooming" refers to a different kind of zooming (pinch zoom on mobile); moving this to Graphics.
Component: Panning and Zooming → Graphics
I was thinking about graphics though. Thanks for re-correcting :)
