it does the trick

To allow for triple buffering. Setting this env variable is restricting the
driver to double buffering.
If that env var fixes things, this points to a bug in the application (wine?)
accidentally using triple buffering but only taking care of double buffers.
Nouveau per default only uses double buffering, triple buffering has to be
enabled in xorg.conf, so with it the issue is not triggered.
