Hi All,
Faced such unpleasant behavior many times.
Eventually made a sample file with the problem.
Could anybody confirm they have the same jumping of the dimension?
P.S. System info included.

ATTENTION:
Desktop is using the slower, less reliable integrated graphics device and probably needs a configuration change.
There is only one monitor detected, but it’s connected to the slower, integrated graphics video port.
- Recommended: Unplug the monitor and plug it into one of the video ports on this device:
[NVIDIA Quadro RTX 5000]
- Any hardware configuration or cabling changes you make will require that you restart Rhino.
