Description Beth Dakin 2012-09-17 11:37:20 PDT
In https://bugs.webkit.org/show_bug.cgi?id=96846 I enabled layer for fixed position elements for DrawingAreaImpls (which is good) but accidentally un-enabled them for TiledCoreAnimationDrawingAreas. We need that code in both classes.

This change caused the text in the bottom bar at <https://bugs.webkit.org/attachment.cgi?id=167493&action=review> to lose its subpixel antialiasing. Perhaps this is expected, but it’s worrisome that ever since the “ugly text” issue was introduced, it seems to have only gotten worse.

This also caused bug 98578 and bug 98579.
