[Mesa-dev] [PATCH] mesa/st: Fix piglit read-front with new drawable invalidation

2011-07-07 Thread Thomas Hellstrom
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 ht
