The snap version includes a software render feature. Maybe you're using this?
This could be slow.
I'm not sure how to verify this, but it makes sense that hardware acceleration is not being used.
The Debian package must use hardware render. Intel ARK doesn't show
much information about your CPU's graphic[1].
Maybe this CPU is too old? (run `anbox system-info` will give your some info)

Not sure if that provides any insight to help solve why the mouse/keyboard won't work with packaged version. I'm comfortable that its plausible the CPU is too old, albeit, the PC is circa 2010, so old, but not that old.

And I'm not sure if anyone tests anbox with XFCE, the integration with
XFCE may also be a problem.
