Comment # 2 on bug 101739 from jan.p57@gmx.de

I also have this problem. Is there a way to force/override Z_ORDER to LATE_Z,
at best per application, so that I can try whether this has any effect?
If not: what other way is there to test it? I am willing to e.g. patch, compile
and test some code if somebody tells me what to do, no promise when I'll find
the time for that though.
