Ubuntu 20.04 LTS and BricsCAD V22

I have been working with this combination for a month now. I have had many crashes and do not know what the issue is. I am moving back to stable Ubuntu 18.04 and V20 BricsCAD.

The crashes happen when I select more than one block for editing.

from the /var/log/kern.log file, looks like a graphics issues.

  • I'll try apt get update, upgrade first, then report back
  • After the apt-get upgrade, BricsCAD V22 continued to crash. I'm moving back to V20 for now.

    Just an observation, but it looks like there was an added feature, when you select two block objects it gives you an arrow between the two blocks. After selecting two objects many many times, over and over again, the crash happens
  • Hello Cnut, does the crash also happen if NEARESTDISTANCE is disabled (value zero)?
  • Hello Cnut, does the crash also happen if NEARESTDISTANCE is disabled (value zero)?

    I will try this, thanks.
  • After setting NEARESTDISTANCE to zero, no crashes so far!
