Thanks for letting us know. Sounds like a problem in the lanczos filter=
. There=20
are two possibilities:
1. It did not get activated on your system before and now it gets. In t=
hat=20
case we should adjust the lanczos filter to ensure that it doesn't get=20=

activated
2. There is a change in mesa which causes the regression. That might be=
 a bug=20
on our side or on Mesa's side. Last time we had such an issue the bug w=
as on=20
our side.

So the most important info at this moment is to know whether the Lanczo=
s=20
filter had been working for you before.
