Can we use SVG to make a smooth image?

Comment 3

Isn't this arrow drawn by native theme code? This seems more like a platform bug.

Comment 4

[Wesley Johnston (:wesj)]

Not native theme. We use SVG background for this. I talked to dholbert about it, and at some zoom levels, svg for background-image can do this. We likely will have to restore our old XUL-Fennec hack here :(

This is no longer an issue with the latest Nightly.
