• Status: RESOLVED FIXED

Screenshot shows the described bug; WebKit is shown to the left, with the same page shown in the current release of Safari to the right.

Please visit http://www.careyblyton.com/ and look at the right of the page. The 'Quick links' column is separated from the main body of the page by a vertical rule-off comprised of alternating solid blue/pink blocks. The vertical rule-off should look exactly the same as similar horizontal rule-offs elsewhere on the page, but rotated vertically. The vertical rule-off is generated by border-image (with a fallback to -webkit-border-image) with 'repeat' enabled.

In the current release version of WebKit (i.e. Safari 8.0.6 on Mac OS X 10.10.3 and other current WebKit-based browsers), this border image renders perfectly. However, in the current WebKit Nightly build, the rendering is seriously broken: the border image appears to be scaled rather than repeated, such that the single graphic component (which should repeat) is stretched to the height of the border, and the width of the graphic is also significantly too wide.
