I have a super simple wedging setup that works fine on Mac. On Linux the same file looks fine in the viewport if I select a workitem, but inspecting it in GPLay shows something with totally different geo (like if the actual saving to geo goes a totally different route from what is shown in the viewport). Then if I render this geo, I will have a third representation! (and yes, I clear data on disk all the time to make sure it is not that)

I am at a loss here. Where should I start looking?
