Cogl previously tried to cache the currently bound texture when drawing through the material API to avoid excessive GL calls. However, a few other places in Cogl and Clutter rebind the texture as well so this can cause problems. This was causing shaped windows to fail in Mutter because ClutterGLXTexturePixmap was binding a different texture to update it while the second texture unit was still active which meant the mask texture would not be selected when the shaped window was drawn subsequent times. Ideally we would fix this by providing a wrapper around glBindTexture which would affect the cached value. The cache would also have to be cleared if a selected texture was deleted. |
