Ah you must be using all of the video memory for the primary surface and the surfacemanager apparently doesn't like chunks with length = 0. This has one possible problem. If you use all of the memory for the primary surface and then allocate a video-only surface they will overlap. I don't see any problem with allowing the chunk length to become zero in this case. I'll send a patch... -- Ville Syrj�l� [EMAIL PROTECTED] http://www.sci.fi/~syrjala/ -- Info: To unsubscribe send a mail to [EMAIL PROTECTED] with "unsubscribe directfb-dev" as subject.
