I just recently purchased a license for Lightburn for use on a computer (windows 10) and laptop (ubuntu 20.04) and I’m having an issue with preview window on linux that I’m not having with the windows version. When I turn off the offset fill, the preview window pops up normally and I can see the estimated time for both OS versions. For the offset fill on Windows 10, I get a message saying it is calculating paths for offset fill before showing the preview window. However, on Linux, I click the preview window and it just stops working. There is no dialogue saying it is calculating the path or indication that the software is working. I usually end up having to force quit LB to exit.
Please let me know if anyone else has run into this issue.
