Let me put it form the PoV of a user:
the program has a problem. It provides an option to start in a mode dedicated
to workaround issues, and pin down specific problems - yet, the mode suffers
from the same problem, and thus is useless.

This, actually, is more deep problem: the Safe mode wizard uses the same
LibreOffice rendering machinery as LibreOffice itself (well, with some specific
configuration known to be mostly safe), so any problem affecting that
configuration will make the wizard useless.

My feeling is that the wizard should be more low-level, and rely on basic OS/WM
features, without need to rely on possibly problematic code. So, my point is
not to disable/enable some other flags in LO rendering machinery, but bypass it
entirely.

This is offtopic here, though.
