[Tracking Requested - why for this release]: Regression

and blurry text in some places like select dropdown menus etc. probably due to Skia usage and its not fixed very long time standing bugs about blurry fonts in text...

If you're seeing something that has existed for a very long time, it sounds like a separate bug.

This looks like bug 1314803. The right values are being chosen in the content process (you can see Direct2D is enabled), but about:support only shows the UI process. We're going to have to report on a per-window basis, or report content and UI separately.

Kinda, but this reveals it now completely, due to Skia rendering, not Direct2D,
but I will diagnose it more deeply and report back maybe in new bug.

Tracking 52- for this dupe.

[Liz Henry (:lizzard) (relman/hg->git project)]

We have to change the status flag to something that isn't "affected" for it to fall off the engineering/relman triage.
