Debian, how to tell apt to ignore a specific package it thinks is broken?

After installing the package xfce4-screensaver, apt and Synaptic keep telling me it's broken and sometimes even trying to automatically uninstall it. Because it has missing dependencies that it can't resolve because I'm on stable and, for whatever reason, it and some of its dependencies aren't in the stable repository. I just went and manually got the .deb for xfce4-screensaver from the testing repository and installed that, and even without those dependencies it's still working exactly as intended (or if there are actually parts of the program not functioning correctly because of this, then it's all stuff I was never going to use anyway) but it would be nice to get it to stop complaining every time I do almost anything with apt or dpkg

You might want to run 'apt --fix-broken install' to correct these.
