User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.101 Safari/537.36 Steps to reproduce: http://jsfiddle.net/yG4Qc/ see this fiddle for the simplest setup I could come up with to reproduce the result. Dragging either the image or the text (highlighted) will show it offset 50%. Double clicking on the input box to get suggestions for autocompletion also shows up offset. Actual results: Highlighted text and image shows up in the wrong position when dragged. Autocomplete suggestions below the input field shows up in the wrong position as well. I have also seen it happen for <select> boxes, but was unable to produce a fiddle with that behavior. Expected results: Same behavior you get when you remove the translateX

I have tested the above fiddle in Iceweasel 17.0.9 on Debian, and FF24.0 on both Windows 8 and Mac OSX, all with the same result.

About autocomplete, it's bug 467442. So the other issue is probably reported. Closed as dupe.
