Can you tell me which version of Linux did you use ? I test it on Linux Mint and pop is and everything looks fine. With more details I will be able to find a fix.
Everything seems to work as intended on linux mint 18.2. I will try to create a virtual machine to test on 19.1. Can you tell me if you use the nvidia drivers, intel or amd ?
I think I fix the issue, it seems to been an export issue. I not able to test it on linux right now, but I think the jump physics will now work. Don't hesite to give me your feedback.
