When loading Google News on Android now, our text renders very poorly and looks like it is being bitmap scaled rather than drawn at the correct size.
I'm seeing this in a Linux desktop Fennec build too.

Trying nightlies: 7th - fonts ok 8th and 9th - I can't run them on my device due to bug 632908 10th - fonts are bad P.S. Comparing builds with dougt, at one point yesterday we were building the exact same changesets, but I was seeing the bug and dougt was not. Only difference we could see in the build settings was my build was a debug one. Very odd.
I can see this in desktop in a build from m-c 682d008059c6 (afternoon on 2/9). I'm starting a bisect to narrow down the regression range.
My bisect isn't finished, but I've narrowed it down to this range: http://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=ffe65159d&tochange=d0ea866f so it looks like bug 586683 is the culprit.
My bisect says that http://hg.mozilla.org/mozilla-central/rev/b0512b9a8c11 is the first bad revision. I suspect this is incorrect, since it looks like that changeset should not alter any behavior; perhaps I mis-marked one of the revisions that I tested. The regression range was definitely somewhere within bug 586683, however.
Writing a reftest for this is a bit tricky. It would be very easy to extend bug 624636 to allow setting content resolution, but it would take a fair amount of new code to allow setting a view transform in the browser, on the shadow layers. There's probably a cleverer way to check this with only the content resolution and maybe CSS transforms. Homework problem!
