Lag while dimensioning

Hello there.

Has anyone experienced a significant lag while dimensioning objects ?

I get a 1 second lag after clicking each node and it's almost impossible to double-click to end the dimension string. 

I am on windows 21H2, very good computer specs. This doesn't happen if I open the file on another computer.

I had this experience last week while trying to dimension storey levels in sections / elevations. Annoying.

Here is another post about a similar issue: Sizing running slowly.

I found the guilty object: it's a morph of a bicycle track. When I save it as an library part it's only 1372 polygons and still makes dimensions lag.

How can I optimize this ?

Sorry to revive this post, but how did you know that specific morph was causing the problem. We have a similar issue where the dimension tool is lagging.
