Darren, I can't reproduce this (on Mac, with native theming both on and off), but this might well be OS-specific due to native theme rendering.  Can you please attach an HTML file that shows the problem for you?

Attachment: A dirty testcase

The select is set with a border-radius and a border-color.

Martijn, Ria, do you see this on Windows?  If so, can you or Darren narrow down when the problem appeared, perhaps.

I see this on Windows 7 too (latest trunk). I dont have any time to look for a regression window, but it works in beta 5 though.

I can't reproduce with the 'dirty testcase'. This is the screenshot of what I'm seeing.
This is tested with today's (20100914) trunk build.
I also tested with the old win95, I can't reproduce it in there, either.

Martijn, is the "can't reproduce" on Windows 7?

Comment 7

[Martijn Wargers (dead)]

Yes.

I enabled HA and the arrow is now visible. Turning off HA and it goes away.

Uh.... really?  A correctness bug _fixed_ by hardware acceleration being on?  ;)

Here is a screenshot showing the arrow with hardware acceleration on a 7800GT graphic card.

That's the range in which we switched from -moz-border-radius to border-radius as the property name.  If you use -moz-border-radius, does the problem appear in older builds.

Probably bug 595842, bug 596205 (this bug), and bug 596271 are related.
