In that bug, we're opting to bypass anti-aliasing for clipped layers, because its a potentially messy case. This bug is a follow-up to 80806 to add anti-aliasing support for clipped quads. David and I talked offline. Some options to consider: 1. Draw the bounding box of the clipped geometry itself, and push the transform complexity to the texture coordinates. 2. Figure out the correct inflation amount in local space, that corresponds to 0.5 pixels in device space. It is possible to issue the original un-transformed quad to the GPU, and the GPU will handle correct clipping. 873193 1 shawnsingh 2013-04-10 13:22:47 -0700 moved to chromium side - https://code.google.com/p/chromium/issues/detail?id=230042
