           Summary: [chromium] premultipliedAlpha WebGL context attribute
                    is ignored.
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebGL
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: jbauman at chromium.org


The premultipliedAlpha context attribute is ignored, and all webgl contexts are essentially treated as having premultiplied alpha. This affects Chromium's layer compositor, drawImage, and toDataURL. I have a patch that should fix this.
