Why is there a crack in the bottom-right corner in the non-rotated case? It looks like a serious problem.
Yeah, that could be an issue. Created attachment 25890 [details]
Borders with alpha
It would also be nice to fix the issues when using rgba() colors as borders (see screenshot).
Comment on attachment 25890 [details] Borders with alpha Bug 21835. Hyatt says that we can't just turn on AA for borders; web authors rely on the per-pixel rendering. We may be able to turn on AA if the element is transformed, though. We think this makes http://unevengoogle.com/ look bad. Borders used for "pixel art": http://www.infimum.dk/HTML/slantinfo.html Another reason to do this is that we draw solid borders with rects (antialiased), and groove/inset/outset borders with polygons (non antia-aliased), so if you change the border style, you go between OK and crappy rendering. |
