Linux console error

system:Fedora 29
version:Ignition 8.0.3
When the vision is running has a console error.
How to resolve it?

This is an error from the JxBrowser library used in the designer for Perspective. Unless you actually notice anything not working, then it’s likely just an overzealous logger. We are in the process of upgrading the designer to use the newest version of JxBrowser, which may help with this issue, but it’s most likely not a significant problem at all.

Ok,I see.
Thank you!
