I don’t see anything in the suggested topics that answers this, so here goes:
My (really) simple animation looks good in 1.2.2 but the same file loaded into 1.3.11 is really lousy. If I look cross-eyed at the canvas (OK, I turn off one layer) the rendering of the canvas starts all over again for 1-2 minutes.
What am I doing wrong? Did I miss a memo or an email?? Is there an option or preference that needs to be checked or unchecked???
