Top borders seem to be a pixel too thin. This is especially noticeable in the thin border in the above URL.‰

This has been identified as a rounding issue with borders that are "thin", "medium" or "thick".

I don't think it all has to do with thin, medium, and thick. The left border in http://www.w3.org/Style/CSS/Test/current/sec412.htm is a pixel too thin on its left side (note that the pixel ruler is 2px off!). In other tests: sec5513b: The thin border on the inline element is thinner inside the table. sec5515b: The border is thinner on the bottom and the right outside the table and thinner on the right inside the table. sec5522: The thin maroon border is thinner on the bottom and the double one varies by side. However, some of this may be related to bug 591.

Setting all current Open/Normal to M4.

All the problem in the sec55* pages are now fixed, I think, except the double border in sec5522.htm

Now the top border in sec5515 (the above URL) is a px too thick, instead of too thin. Was this corrected in 2 places? (i.e, gfx code and workaround)

per leger, assigning QA contacts to all open bugs without QA contacts according to list at http://bugzilla.mozilla.org/describecomponents.cgi?product=Browser

The style code has been changed so that borders are computed in pixel instead of points. Any rounding issues left are in the rendering code...

I don't see any rounding issues left...

kevin, can you confirm this and mark it fixed if necessary?

Looks fine. Brought up URL, examined the borders with ZoomIn.exe. Marking it as fixed.

Verified fixed.
