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.

    This issue almost made eclipse unusable for me.
    In my case i am on X11 not Wayland, which i think is relevant. Anyway, set this variable before starting eclipse e.g.

    WEBKIT_DISABLE_COMPOSITING_MODE=1 ./eclipse

    Another issue this fixes is the welcome screen (Help -> Welcome) was blank.

    When running eclipse from the console, every time i hovered over something, i would get an empty dialog, and this error in the console

    WebKitWebProcess:1211824): Gdk-ERROR **: 17:31:08.234: The program ‘WebKitWebProcess’ received an X Window System error.
    This probably reflects a bug in the program.
    The error was ‘BadValue (integer parameter out of range for operation)’.

    Try switching themes to Dark with Reduced Palette.

    I was getting this as well when using the Dark theme with Default color and font configuration. But I switched the color/font configuration to Reduced Palette and the tooltip started working! Hope this helps.
