Here was a solution Trimble had provided to someone else having the same issue, this should work for everyone. This problem only seems to happen when you are working with your files on a server.
Step 1:
Be back on 2025.20 if you aren't already
Step 2:
Click the HOME button at the top.
Step 3:
Click on the Quick Access Toolbar "Chevron" arrows far top right corner on the HOME Ribbon
Step 4:
Click on More Commands

Step 5: (final step)
Locate exactly the "Open Project Folder (Custom)" with the folder in front and X it out or delete it.

Having this command on your toolbar causes TBC to constantly look to the server causing the stutter.
Let me know if for some reason this solution ripples and causes a different problem.

After updating to version 2025.20 there is a bad lag. Pointer moves normally for a few seconds and then stops for 10 to 15 seconds. Its not just a display problem as event viewer shows TBC as unresponsive during these pauses. I rolled back to 2025.10 and the problem is gone.
Anyone else having this issue?
