Very similar (but visually not exactly identical) glitches exists without nine,
but there are workaround in wine:
[HKEY_CURRENT_USER\Software\Wine\Direct3D]
CheckFloatConstants="enabled"
which helps with it. This key does not make a difference with nine.
There are no such problem with nouveau (750ti) here, os ubuntu-16.04 with oibaf
and commendsarnex ppa.</pre>
