Comment (by myan18):

 Replying to [comment:2 mf2k]: However I did not get the answer. What or
 who is "upstream"? Will it be fixed within a certain time frame or the
 problem will be hanging indefinitely? I am seriously considering to get a
 backup Windows machine just for being able to use Povray...
