Can you try 6.5.3 now?
> Maybe should I wait for Mesa 7.0.2 release?
6.5.2 is still available from
in the meantime.
Since you provided a program to reproduce, we should be able to locate
which commit broke this (with git-bisect between 6.5.2 and 6.5.3 or
6.5.3 and 7.0.1 depending on your reply to the first question).
