Just as part of circumstantial evidence, I'd say that the G5 from Rocky's screenshot is at least not the default Apple X11 build (with the default settings). I mention this as those of us with macs are probably using Apple's X11 (I once used the XFree86 version for Darwin, but convinced myself that it had problems -- it was probably just a bug in a class project in the end) so if there is a difference between the two, this seems possible. With Andrew's new file display though, maybe you can test that theory ( and separate a possible render bug from a possible display bug ).

uname -a

I just checked out a fresh copy, set the build mode to Release, and it worked fine.

Note that you get a significant performance improvement by adding - malign-natural to the set of command line flags. However, it doesn't work on the old gcc, so we didn't make it the default.

Andrew, or someone else with a Mac - can you check the same thing?

I'm trying to get manta working on a G5 Mac here. I've built the main trunk with a RELEASE build type that causes a whole lot of compiler flags to get used. The resulting binary has some issues, as illustrated by the attached image. When I compile with only "- O3" the image looks fine. Anyone seen this before?

"g++ -- version" reports powerpc-apple-darwin8-g++-4.0.0 (GCC) 4.0.0 20041026 (Apple Computer, Inc. build 4061).
