mesa/st: Fix piglit read-front with new drawable invalidation v2
When the state tracker adds a front buffer, nothing triggers a validate drawable call, since the state tracker manager is never notified. Force a validate drawable call by invalidating the framebuffer's stamp, so that the window system's renderbuffer (if any) is picked up. This fixes bug 38988 https://bugs.freedesktop.org/show_bug.cgi?id=38988 Signed-off-by: Thomas Hellstrom <[email protected]>
