Hello Chris,
thank you for the reply!

As for my humble case it would be perfectly enough to have a 1.10.3
with the pixman_image_ref patch applied.
(The last time I checked it wasn't in the 1.10 branch yet.)
But if 1.12 is the way it goes, I'll just wait and/or think of a
workaround (like blacklisting certain versions for multithreading).
