Screenshot showing unused part of available screen height

SUMMARY
KMyMoney uses only half of the available screen height

STEPS TO REPRODUCE
1. Open the application, e.g. page "Übersicht" or "Kontenbuch",

OBSERVED RESULT
Starting with KMyMoney 5.2.0 the application is using only approx. 50% of the avalailable screen height - the lower part is unused (see attached screenshot). I don't see a possibility to adjust this.
I experience this behaviour under Linux (OpenSuse TW 20251006 x86_64) since first update from 5.1.3 to 5.2.0. Current version is: 5.2.1-122.11-x86_64.
Under Windows 10/11 5.2.0 does not show this behaviour (Version 5.2.0-aac0449), but 5.2.1 is now also having this issue (last checked with Version 5.2.1-4b18ddd).

EXPECTED RESULT
Full available screen height is used.
