           Summary: contained div with right 0 sometimes overlaps parent
                    div
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
               URL: http://jsfiddle.net/7RUWQ/
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: andrewbachmann at yahoo.com


When viewing the attached URL at various zoom levels, the display changes and sometimes the right hand top of the button loses its border.

The attached image shows the effect in Chrome 22.0.1209.0 (146837) using WebKit 537.1 (@122718)

This manifests in our application with no zoom on some buttons but not other buttons.  It was first experienced in Chrome 21.0.1180.41 (Official Build 146467) beta using WebKit 537.1 (@122379)

It works okay in Chrome 20.0.1132.43 (Official Build 143823) beta using WebKit 536.11 (@121111)

Guess: subpixel rendering issue?

Bug 90097 looks relevant but the fix for that didn't fix this.
