Use all screen realstate in scrolling window manager

[GreenBackBone]

Im using Arch Linux with Niri scrolling window manager
in this manager all windows spawn using half the screen
the thing is that when i maximize sweethome3d window
the actual usable realstate stays in half
is there a way to have it use the full mazimize space?
i attach video for visual explanation

thank you for your time

The program fails to calculate the real size available, most likely because it fails to recognize the dpi, perhaps on a high dpi display. There is a custom setting which allows to override the default scaling, see this post and experiment different values until you get the expected result:

If it doesn't work at all, you may try to reduce the dpi to a standard value.
MS WINDOWS allows to force the dpi to a specific value when a target program is executing (compatibility option), perhaps you can achieve the same on Linux (using some additional software?).
