I checked and both versions are the same, V0.9.22. I did some more digging and I’m not sure I understand what I’m seeing. A design was created using LB involving a lot of calligraphy (text) that made the offset fill the faster option. Both Win10 and Ubuntu worked when the text was straight (0 deg rotation. However, when rotated to 90 deg. (to better accommodate the bed size), windows seems to handle it okay but linux still locks up. I did originally have a file issue (file was somehow corrupted that caused both machines to lock up) but after fixing that issue, the windows machine can cope but my linux laptop opening the same file locks up.
I am running the windows version on newer computer running Pentium j4115 w/ 6GB RAM and the laptop(linux) is running on an older laptop with i7 3520M w/ 8GB RAM.
