           Summary: [Qt] Assertion fail in
                    RenderLayerBacking::paintIntoLayer when texmap is used
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: UNCONFIRMED
          Severity: Normal
          Priority: P2
         Component: Layout and Rendering
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: kwangyul.seo at gmail.com


Qt WebKit fails on the following assertion when texmap is used:

void RenderLayerBacking::paintIntoLayer(RenderLayer* rootLayer, GraphicsContext* context,
                    const IntRect& paintDirtyRect,      // in the coords of rootLayer
                    PaintBehavior paintBehavior, GraphicsLayerPaintingPhase paintingPhase,
                    RenderObject* paintingRoot)
{
     if (paintingGoesToWindow()) {
         ASSERT_NOT_REACHED();
         return;
     }


If we skip these 3 lines, accelerated compositing seems to be working fine. I was able to run http://www.webkit.org/blog-files/leaves/index.html successfully.

#if !USE(TEXTURE_MAPPER)
    if (paintingGoesToWindow()) {
        ASSERT_NOT_REACHED();
        return;
    }
#endif
