I used to get that kind of issue in older versions of TBC on my old Laptop - I never tracked it to anything specific - it was like Go To Meeting or Hangouts or one of those tools would trigger the issue to happen and once it started I had to reboot. I ended up scrubbing my computer and reinstalling everything because it became a real problem - since then it has all been fine again - so it is likely that you have something interfering with TBC in the background.
It could be things like Google Drive, Drop Box, One Drive etc. or some other service that is getting in the way.
Unfortunately this is not an easy thing to resolve - I would open a support ticket with your dealer and have Trimble Support try to help you diagnose the issue - this is not normal unless you have lines set to show as linestyles instead of all as Solid (Toggle at base of screen) - if that doesn't help (which can cause the issue you are seeing then I am not sure what to suggest.
I have not seen this issue in 5.32 -if you share a project setup as it is when you are seeing the issue I can run a check for you to make sure it is not data related - but you are saying all projects are doing it which is strange for sure.
