This code in webkitWebViewBaseRealize is wrong:
#if USE(TEXTURE_MAPPER) && PLATFORM(X11) && !USE(REDIRECTED_XCOMPOSITE_WINDOW)
if (DrawingAreaProxyImpl* drawingArea = static_cast<DrawingAreaProxyImpl*>(priv->pageProxy->drawingArea()))
drawingArea->setNativeSurfaceHandleForCompositing(GDK_WINDOW_XID(window));
#endif
You can see it improperly casts the GdkWindow to a GdkX11Window without checking to make sure it's X11. And I see it's guarded by USE(TEXTURE_MAPPER) so it's indeed not enabled by default, that explains why it works in rawhide (where I reenabled USE_OPENGL after our recent bugfixes) but not F24 (which I accidentally did not reenable USE_OPENGL until just now).</pre>
