[Tracking Requested - why for this release]: Regression

STR:
1. Open some forums like for example - http://board.pl.ogame.gameforge.com/board790-z-ycia-uniwers-w/board264-dyskusje-i-dyplomacja/board1407-did-u68/
2. See that grayscale antialiasing is used instead of sharp subpixel antialiasing

Going to http://board.pl.ogame.gameforge.com/board790-z-ycia-uniwers-w/board264-dyskusje-i-dyplomacja/board1407-did-u68/1354881-rekordy-uni68/index6.html could produce the same issue, but only when the page is at the bottom, scrolling up fixes the issue

Looks like we're failing to detect the layer as opaque. I've backed out bug 1012752 because I need some more time to investigate this.

This is works for me, because of the backout of bug 1012752.

Since this was fixed by a backout, I don't think we need to track this for 50.

Virtual_ManPL, can you reproduce this bug with the new try build from bug 1012752 at https://treeherder.mozilla.org/#/jobs?repo=try&revision=1f82832d45b2 ?
I've only got it to reproduce when I scrolled all the way to the bottom, and that part is fixed for me.
