Summary0029191: Visualization - viewer rotations are not smooth
DescriptionWhen displayed shape is flat, after resetting the view so that the shape becomes parallel to the screen, rotations of the viewer by mouse become not smooth: even small movements lead to strange jumps. Sometimes parts of the shape get clipped by front or rear clip planes.
Steps To ReproduceDRAW script to prepare scene:

pload AISV
restore [locate_data_file bug29191.brep] a
# when sub-shapes are displayed separately, effect is more noticeable
foreach s [explode a] { vdisplay $s }
vtop
vfit

I do not see easy way to create a test case (it is interactive operation), thus assume we do not need one
