I'm using SDK 3.4.1.GA. Problem is on iOS > 6 with iPhone 6 and 6 Plus.
I think, the @3x images are ignored. I tried several things around. Setting backgroundRepeat to false, using @3x image, setting the width of the table (standard is Ti.UI.FILL). But nothing works.
Attached a screenshot of my problem: example
Hopefully, someone of you has a suggestion!
