1032658 - sfgate.com slideshow photos are black and do not redraw when scrolled part way off screen

Status: RESOLVED DUPLICATE of bug 1025914

(Core :: Graphics: Layers, defect)

Description

[Chris Peterson [:cpeterson]]

STR:
1. Load http://blog.sfgate.com/stew/2014/06/30/why-you-should-move-to-san-francisco
2. Scroll down the page so that half of the first slideshow photo is off screen.
3. Then scroll up to view the slideshow photo again

RESULT:
The off-screen portion of the photo is black and does not redraw.

I bisected this regression to this pushlog for Nightly 32 build 2014-05-14:

https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=971b840c40ff&tochange=35af5d1c97c3

This is the same regression pushlog that I reported CSS flashing bug 1020556, which is likely a regression from scrolling invalidation bug 1008301 and seems to be related to the fact I have a MBP with a HiDPI/Retina display.

This looks very similar to bug 1025914, duping. I'll back out bug 1008301 until I've fixed the regressions.
