Is your menu OK after closing preferences,
No.
or could it be related to http://bugzilla.lyx.org/show_bug.cgi?id=5168
No, it is not. I can also reproduce the bug by manually putting \use_pixmap_cache true into the preferences file, and it also persists after a restart.(This is actually where I came from, because LyX crashed with my preferences transfered/converted from 1.5.)
