That's what I've been missing. So indeed it looks like the X rendering code would have to be extended to handle this correctly. Or might there already be code for this in related to the double buffering extension? Meanwhile, using shadowfb instead of the mi shadow module seems to keep the X display outside of the 3D window from getting corrupted at least. -- Earthling Michel Dänzer (MrCooper)/ Debian GNU/Linux (powerpc) developer XFree86 and DRI project member / CS student, Free Software enthusiast ------------------------------------------------------- This sf.net email is sponsored by: With Great Power, Comes Great Responsibility Learn to use your power at OSDN's High Performance Computing Channel http://hpc.devchannel.org/ _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
