1580703 - Enable browser_offscreen_image_in_out_of_process_iframe.js on WebRender windows

Status: RESOLVED FIXED

(Core :: Layout, defect, P3)

Description

[Hiroyuki Ikezoe (:hiro)]

browser_offscreen_image_in_out_of_process_iframe.js is going to be introduced in bug 1541705, but unfortunately the test seems perma failure on the platform. For now, I am going to disable the test on WebRender on Windows. This is a bug to investigate why it fails there.

I can reproduce this failure on my Windows laptop, 4000px is not sufficient there. We should explicitly set the display port by nsIDOMWindowUtils.setDisplayPortForElement so that the test would be independent from platforms.

I think it would be better to just increase the 4000px to something bigger rather than force a displayport size since the 4000px is something that webauthors can change, whereas the displayport is not so its testing something closer to what users see.
