Ok, I do not understand much about OpenGL programming. Where the hack you are
talking about is located? In kwin or in the screensavers?

I followed some of those discussions. Well, it seems there are people
interested in using light-dm instead of kdm, how that would affect moving
screenlocker to kdm? What about this approach to move it to ksmserver? If the
locker crashes the user is just logged off, there is less security risk, just
the possible data loss is the problem :-) Specialy if you use one of those
crazy optimizations filesystems use to make them look good in benchmarks.
