STR: 1. Go to https://static.mozilla.com/moco/en-US/images/mozilla_eoy_2013_EN.svg 2. Scroll down and back up. Repeat as necessary to reproduce bug. Expected results: After scrolling back up, things should look correct. Actual results: Every now and then, the top row of tiles has incomplete content after scrolling up. See attached screenshot.
I suspect this is a regression.

Update webrender to commit 9f21ee5dba0694818a1e2e46d95734ede281447c Screencast: first bad (left Nightly icon): One or more tiles(?) are often displayed with a delay or are only shown in part. Scrolling the page causes massive checkerboarding(?), so everything is white at first. last "good" (right Nightly icon): The page is just scrolling with a huge delay.

(In reply to Sotaro Ikeda [:sotaro] from comment #6) > https://github.com/servo/webrender/pull/3398 in Bug 1492241 addressed the > problem for me. The fix will be in m-c soon. I rechecked the problem. The problem was not addressed. With the patch, it just appeared differently.
I wonder if this might be caused by the mPaintRect changing.
