I've got a scrollable area that contains a number of Group Boxes.

When I reduce the window size the vertical scroll bar appears and I can scroll through the display. That's fine but the first frame in the top group box shrinks so that the text doesn't display correctly on some Linux systems - Ubtuntu 24.04.03 (Noble Numbat) has this problem, whereas Lubuntu and Linux Mint work OK. Windows and macOS are also OK.

See attached image.

I think that Noble Numbat uses Wayland.

This probably also applies to releases older than 6.10

The .ui file for this is also attached.
