after running LD_DEBUG=all snap list in the previous comment: grepping for X11, I see that it is used by something called "AppProtection", which is apparently related to Citrix workspace WFH software (some sort of anti-screenshot program). I uninstall Citrix Workspace, and this problem with snap went away.
