Ah, so the r100 driver is unchanged there? I'll look into moving the changes over, but it would probably be easier for Brian or you... Meanwhile, I've made some funny experiments. The bzflag problem happens reproducibly on the first run after the X server was started, and then seemingly randomly. Or maybe not so: I kept starting bzflag and exiting immediately, and it seems to happen exactly every 21 times! I'm sure that and the fact that it happens every time with the texmem branch is trying to tell me something, unfortunately I don't know what... I hope it rings a bell with anyone. -- 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: ApacheCon, November 18-21 in Las Vegas (supported by COMDEX), the only Apache event to be fully supported by the ASF. http://www.apachecon.com _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
