Since we now cache windows in the X server, we don't really need to cache them here. Since we are redirecting windows in most cases, we're not gaining anything except added memory usage. Additionally, remove the clip to screen optimization - if a window is partially off-screen, we still need to draw the entire thing as redirection means we won't get an expose event for it. Additionally, when introducing invisible borders, something accidentally slipped through: we were getting expose events on the invisible borders, and they weren't in the cached pixels rect, so we were painting the theme for them, even if we didn't actually paint anything with cairo. Make sure to clip out the invisible borders instead of just the client rect so that we don't draw if our expose event is on the invisible borders. https://bugzilla.gnome.org/show_bug.cgi?id=675111
