2932	"View transition ""jumpy"""	charles.sindelar@…	Tom Goddard	"{{{
The following bug report has been submitted:
Platform:        Darwin-17.7.0-x86_64-i386-64bit
ChimeraX Version: 0.92 (2020-03-06)
Description
Camera trajectory is discontinuous for large view re-orientations. The following sequence below reproduces the problem. This seriously compromises my ability to make movies in ChimeraX. I have confirmed that Chimera (not ChimeraX) handles the equivalent transition just fine.

zoom 0.5
move x -40 1
view name v1
roll y 180 1
move x 80 1
view name v2
view v1 100
view v2 100
