Ah, ok, didn’t know about this environment variable! Well, both results didn’t change
using this, though, i.e. the app still rendered wrongly.

Yeah, I remembered somehow, but after so many months I had just not been able to
find the correct email of yours from back then. Can you believe it.
There had been SO much traffic…

Well, the white rectangle is perhaps not coming out too large, who knows. I learnt
that Inge had already changed the sizing of the tile (and thus its shadow) in the
version he used to produce the Linux screenshot…

Anyhow, it seems as if we’ve got a real OSX issue here. Strange, as you’re using
also shadows in your gorgeous Palapeli!

I’ll have to introduce a new subpart parley-devel in order to investigate this
further next week.

Thanks Ian for responding.
