Eclipse tooltip on Ubuntu 22.04 is always empty

I'm using Ubuntu 22.04 and Eclipse IDE (09.22). Every time I show the tooltip (for javadocs or so) it's just empty. I've seen people talking about similar problem and one of these solutions is to install gnome-color-chooser but I'm worried color-chooser is not right for jammy (Ubuntu 22.04) : I tried to install the deb but there are too many dependencies to be installed (who need dependencies on their own). Does anyone have the same issue? or know how to solve it? thank you.
