What happened?

When hovering a hop in Hop GUI, the tooltip is shown at the top left of the window, rather than next to the hop itself, see the example below:

Using Ubuntu 22.04.4 on VirtualBox 7.20 in Windows 10 host, no particular graphics options enabled

I have deleted the comment, thanks @dave-csc !

Update: the same issue happens after upgrading the OS to Ubuntu 24.04.1 (with the same configuration for the other tools).

Setting the GDK_BACKEND environment variable to x11 within the hop-gui.sh script (see screenshot below) can help resolve compatibility issues when running HOP on Wayland by forcing GTK-based applications to use X11 rendering.

Related issues:

• [Task]: document Linux + wayland issues with Hop Gui, point users to X11.  #4619
• Wayland support in experimental state despite being introduced in stable releases eclipse-platform/eclipse.platform.swt#639
• Shell.setLocation doesn't work properly (or at all) on Wayland eclipse-platform/eclipse.platform.swt#790

Patching the hop-gui.sh file indeed solves the issue, thanks @ep9io ✌️

Update: this patch also solves #3783 and #3813 ✌️ ✌️

fixed by #4720

Can we change that to?

    if [ "${XDG_SESSION_TYPE}" = "wayland" ]; then
        GDK_BACKEND=x11
    fi

[ep9io]

GDK_BACKEND=x11

We need to have the export prior to the setting of the variable.

However, good point about wrapping the env param in quotes as that's good practice to avoid word splitting and empty variable substitution. The env param should be set correctly in most circumstances, but there's no harm with what you suggested.
