We are running into rasterization inaccuracies here. This test draws green circles on a green rectangle and assumes that the result will be solid green. Here's what happens with D2D: D2D computes coverage values in floating point so assume that we get a coverage of about 0.112399 or 0.112399*255 == 28.6 green (128/255 == 0.50196) is multiplied by the coverage to get 0.0564702 or .0564702*255 == 14.39 the results of the pixel shader get rounded before blending. So we get (r=0,g=14,b=0,a=29) blending this OVER green gives: 14+(255-29)*128/255 == 127 instead of 128. This doesn't happen with other backends because they typically use integer coverage amounts. We fix it by using ' ' instead of '.' |

To have your bug fix / feature added to Mozilla, you should create a patch and
submit it to Bugzilla (https://bugzilla.mozilla.org). Instructions are at:
http://developer.mozilla.org/en/docs/Creating_a_patch

If you have a question about developing Mozilla, and can't find the solution
on http://developer.mozilla.org, you can try asking your question in a
mozilla.* Usenet group, or on IRC at irc.mozilla.org. [The Mozilla news groups
are accessible on Google Groups, or news.mozilla.org with a NNTP reader.]
You can download nightly development builds from the Mozilla FTP server.
Keep in mind that nightly builds, which are used by Mozilla developers for
testing, may be buggy. Firefox nightlies, for example, can be found at:
