While it does not make sense, that does seem to jive with my idea that
show-fps (which heavily depends on depth-sorting as it should be on
top no matter what) has a issue with transparency, which also depends
on depth-sorting.

I'm not convinced there is not something wrong with the
transparency/depth sorting of show-fps and clearly this is a delicate
issue for GL implementations as it is a hard issue to do correctly and
fast, but no matter what it should not crash.

At least this is ok in this case for now.
