Since drawing with an all-clipped clip doesn't do anything at all, something should notice this and return success early on. Instead of your patch, could you try adding the following at the beginning of _clip_and_composite_boxes()? Thanks (Hm, and I'd be curious how exactly this can happen at all, the higher levels should check for all-clipped earlier, I thought): if (_cairo_clip_is_all_clipped (clip)) return CAIRO_STATUS_SUCCESS; (Sorry, my main work computer broke and I am having some problems due to this)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
