[Chimera-users] Chimera crashes when saving image

Your advice worked perfectly.
I updated to build 27479 from 2009-05-03 and 2D Labels are now visible in
saved images and disabling Pbuffer as suggested in your other mail allowed
me to save really huge images with no problems at all.
Since I decided to use daily builds, I am aware that this bugs are normal
and part of the development cycle, but I happily trade some stability for
cutting edge developments :-)
So my question is: is the general Chimera mailing list the proper channel
for discussing these software quirks from these alpha or beta versions?
Thank you so much

This appears to be a linux graphics driver problem that you see when
using new Chimera 1.4 image saving code that uses off-screen OpenGL
PBuffers to capture images. Chimera 1.3 saves images directly from your
screen and will not have this problem. You can also make Chimera 1.4
use the older image saving technique by starting Chimera on linux with
"chimera --debug-opengl", then turning off the Pbuffer switch in the
opengl debug dialog that appears at startup. Greg Couch in our lab is
working on the Pbuffer code and can provide more advice next week.
