Description
I get the following error when running sudo howdy test in su -, however this error doesn't happen when running in su. I think I might have screwed during the installation process...
Is there a way to fix this?
qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
I've searched for similar issues already, and my issue has not been reported yet.
Linux distribution (if applicable): Debian 12
Howdy version (sudo howdy version): 2.6.1

Research direction
Reproduce sudo howdy test in su - and compare it with su on Debian 12, focusing on the reported Qt display and xcb errors. Done means identifying a concrete cause and documenting or implementing a fix so the test command runs successfully in the affected login-shell context.
