Wrong layout in Kmymoney ledger tabbed view

The layout ledger in tabbed mode view is very very small, less than half a screen.

I tried in tree mode view and list mode view ; there’s no problem in these modes (except I have no icon in list mode view).

I’m under Ubuntu 22.04 64 bits, Gnome 42.9, X11 windows mode, with the latest appimage version 5.2.1-be4919f

Is it possible to correct this bug ?… Thank you.
