We’ve accepted the bug report. I was able to reduce the jitter by inserting a Format Number node and using a smaller font size. Are those changes applicable for your situation?
No, I’m using this for timecode, some of which I want to place in the lower right of a window. Because the numbers are changing 25 times a second reducing the jitter isn’t enough, It has to be zero, so I will just carry on using left anchors for now.
