This issue came to my notice today. In v 3.0 the default of Stroke Space of 3% cause blender to almost freeze up for me, whilest in v 2.93 the performance is … tolerable. The issue link is from someone with a superior platform, so I think it’s worth considering whether there is some other issue here. For example: perhaps too many calculations were added to version 3.0?
At the least perhaps the default (3%) should be reconsidered.
