see also: bug on ghostscript A RH 6.0 alpha system PC 164 LX w Matrox Millenium II with all updates till today. After upgrading to xfig from RH 6.0 it doesnt display any lines or rectangular boxes anymore. A remote running xfig from a RH 6.0 ix86 system (without the XFree updates) does work ok, so I assume its not directly an X problem. I am unsure if the problem started after the update to RH 6.0 from 5.2 or after installing the recent X updates. reverting to xfig from RH 5.2 fixes the problem.
compiling w/o optimization on the alpha seems to have corrected this problem.
