Hi Kevin,

Thanks for testing Hop 2.0 and joining the community!

These warnings are related to SWT, the library we use for Hop Gui, in
combination with the various GTK versions on Linux.
There's no security risk, this is a warning about how the scrollbars in the
UI are painted.
Afaik there are no patches available at this moment. We're constantly
upgrading the SWT libraries and keep working on improving the user
interface, so hopefully, these warnings will disappear in a future release.

In the meantime, Hop Gui should start up and function correctly. Let us
know if that is not the case.

Regards,
Bart
