This bug is caused by a combination of Debian changing the packaging of libdecor to no longer include decoration plugins by default and wl-mirror having a bug that it doesn't correctly handle libdecor taking more than 1 Wayland round trip to configure the surface. You can workaround the bug by installing a libdecor plugin package such as libdecor-0-plugin-1-gtk, which was previously included by default with wl-mirror. The bug has been reported and fixed upstream here: https://github.com/Ferdi265/wl-mirror/issues/74 This bug will be fixed in the soon-to-be-released wl-mirror v0.18.4 and is already fixed in the current main branch of wl-mirror. I will also see that wl-mirror gets another sponsored Debian upload once the release is out since I am not a Debian maintainer and can't upload packages on my own.
