All the original comment says is "set a very large radius and you get rendering artifacts".
Presumably in this case the large dark gray rectangles.
Note that the transitions are a red herring; they're not needed to reproduce the bug.

Is this a bug in nsCSSRendering or underlying gfx bug? I see this on Mac, so I suspect the former...

Ever confirmed: true
Summary: border-radius → Large border-radius not rendered correctly when border widths are different on different sides
Summary: Large border-radius not rendered correctly when border widths are different on different sides → Large border-radius not rendered correctly when one of the borders has width > 50% of border-box
Only IE handles this testcase. It reveals that borders aren't drawn correctly (note the colored areas)

I was wrong: there're cases when "border-width > 50% of border-box" isn't required.
I saved 4 testcases in my dropbox folder. Use the "index" page to open the testcases by direct links

Please correct me / undo changes if I did something wrong with this bug.
