Bug 88149 – [Win] ASSERT_NOT_REACHED() reached in RenderLayerBacking::paintIntoLayer

• Status: NEW
• Component: Layout and Rendering

[Jessie Berlin]

I see it happen for compositing/backing/no-backing-foreground-layer.html when I run the tests on Windows with a debug build.

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