STEPS TO REPRODUCE
1. ensure you have 2 or more disks

3. use keyboard up/down arrows or mouse to select different device (Devices pane on the left)

OBSERVED RESULT
Main window (/dev/<selected_device> -- KDE Partition Manager) changes its size at each Device selection

EXPECTED RESULT
Do not change size))

Can't reproduce it here? Perhaps X11 only bug? Could you try on Wayland?

Cant log in with Wayland, just black screen.
But I've just noticed that removing Information tab from main window layout (either use as separate window or hide) "solves" the problem. 
Also, if Information tab is moved from left pane to bottom, only window width shrinks.

Thanks for the bug report. Unfortunately, these versions of Partition Manager and Plasma are no longer maintained by KDE. Debian advises users to not submit bugs upstream (https://www.debian.org/Bugs/Reporting). It's possible that the bug exists only in Debian at this point. 

Could you report the bug to Debian using the report bug utility (https://packages.debian.org/stable/utils/reportbug)? If necessary, the maintainer of the package will forward the bug upstream.

Thanks for understanding.
