REFTEST TEST-UNEXPECTED-FAIL | file:///c:/talos-slave/mozilla-central-win7-opt-u-reftest-d2d/build/reftest/tests/layout/reftests/bidi/visualmarquee
.html logicalmarquee .html
After enabling reftests for Direct 2D we are hitting this failure in this test suite. http://hg.mozilla.org/mozilla-central/rev/f32afa31a2e1
This looks like a kerning issue.
This does not actually have anything to do with bidi text, or with the Hebrew font used in that reftest. Here is a simplified testcase: loading the following examples into separate tabs and switching back and forth between them, the text can be seen to shift slightly: data:text/html,<html><body><div style="text-align:right">Hello</div></body></html> data:text/html,<html><body><marquee scrollamount="0" behavior="alternate">Hello</marquee></body></html>
This issue also occurs on OS X (bug 561637). On Windows, it occurs with the DirectWrite font backend using either DW or Harfbuzz shaping; it does not occur using the GDI backend.

This should be fixed as a result of smontagu's reftest patch in bug 561637.
