Chris (and Don),
I can reproduce this. It appears that changing between standard views after
editing (not necessarily spinning) will do it. The behavior is actually
different for me with the Apple OpenGL versus ATI. With Apple, the trans color
just disappears, like Chris’s pictures. With ATI, a pattern shows up in the
trans color while spinning, as in the following image (trans-neon green 2x1
plate in center, also note the 43722/3 wedge plates’ outlines don’t disappear
when spinning in the filled-box mode):
One question, Chris, how much performance difference do you see between the ATI
and Apple OpenGL on your PowerBook? I’ve been trying to get some idea of the
extent to which the latter might be making use the G4’s vector unit.

| Don, Congratulations on the 1.0 release. At 800,600 (32bit colors) resolution the ATi driver loads, and then LDGLite switches to the Apple driver (the window behavior and the printout from the terminal is included below) after the window is (...) (21 years ago, 8-Aug-03, to lugnet.cad.dev.mac)
