No, false positives is what you'll get on your approach - proof: the cause for
this discussion.

It's not a fix, thus not a bad fix.
It's a trade-off: we've a feature that will either get you less performance
boost than another feature - or crashes.
Then what's the "regression"?
You suspend compositing instead and get 3 more extra fps in your shooter?
If you can work around the problem in a way so that we do no more get a
"help, kwin crashed after checking this" bugreport about every week,
i'll happily vote for that solution.
inb4: If your solution is "disable it by default and remove the config
GUI", you're asking for a single target ("you") solution - and i'm dead
sure the "secret command to make kwin faster" will show up pretty fas as
well - with known consequences.

It seems Sandybridge is affected by the same root cause (see comment #17 and
comment #43) and it seems Ubuntu/Compiz meanwhile figured this happens =)
