           Summary: <marker> clipped when opacity < 1
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
               URL: http://www.barhams.info/webkit/opacity.xml
        OS/Version: Windows Vista
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: SVG
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: tbarham at sumtotalsystems.com


A marker attached to a path is clipped if the opacity of the path's container
is less than one. Repro can be seen at the referenced URL
(http://www.barhams.info/webkit/opacity.xml), which shows three paths with a
marker attached to each end.

The first path is within a <g> with opacity set to 0.25, showing clipping of
the markers.

The second path is within a <g> with opacity set to 1, showing no clipping.

The third path shows the best, but less than ideal, work-around I have been
able to come up with, which is applying the opacity to each component (the path
and each marker). However, this looks poor in areas where the marker overlaps
the path.

I found bugs reported regarding clipping of various elements when opacity is
less than 1, but none specifically dealt with markers that I could find. This
may be an additional repro case for those bugs, or a separate problem.
