[chimerax-users] crossfade issue

[Elaine Meng]

Great!  It might also work with different sizes of graphics window vs. movie as long as the aspect ratio (ratio between height and width) is the same, but that is also just a guess.  :-)

Best,
Elaine

If so, instead of sending a message here, use menu: Help... Report a Bug and attach the session file as well as the commands that you sent below, and a description of the problem.  That also lets us know the ChimeraX version and type of computer you are using.
