--- Comment #4 from Zebediah Figura z.figura12@gmail.com --- Created attachment 71594 --> https://bugs.winehq.org/attachment.cgi?id=71594 never map persistently
Unfortunately I can't reproduce this on radeonsi.
What happens if you always return false from wined3d_map_persistent(), as in the attached patch?
