--- Comment #13 from Miguel Gomez <magomez at igalia.com> ---
I found the reason of the strange colors showing up on the page. The problem is that we are creating a glcontext for the window whose default framebuffer doesn't have a stencil buffer (neither a depth one). Due to this, when we do stencil clipping on the default framebuffer it doesn't work properly, leaking to the page the last color we painted with.

I'm cooking a patch that creates a context using a GLXFBConfig that is compatible with the one used by the window but having a depth and stencil buffer.
