nanogui: Thread: FLTK/FLNX

Hello All,
We are evaluating the differences between
FLTK/FLNX on microwindows vs FLTK on XFree86
(all on a X86 Linux platform). 

We have noticed some odd differences. The checkers 
demo  in "auto play" is VERY slow. There also seems
to be problems when one checker is dragged over another.

We have verified that these problems exist in the
latest release v0.89.

Is anyone out there working with FLTK/FLNX on top
of microwindows? If so, have you noticed the same
problems?

Thanks,

Mike

I think these speed problems are related to the fast blitting
problems with Microwindows' X11 screen driver and the
image code, which doesn't use blit.  I have received a patch
for the X11 screen driver rewritten for speed, and I'm going
to change to internal image handling code to use blit.  This
should solve the problems.

Regards,

Greg
