--- Comment #8 from clm@martindroessler.de --- Created attachment 61831 --> https://bugs.winehq.org/attachment.cgi?id=61831 Screenshot of different version of the problem
This may not be a bug with wine, since I was able to correct it in game, by going to the system menu, advanced, and selecting my graphics card. Changed from system default to GTX 970 and it rendered properly on all my characters, from that point forward.
Are you sure regarding the proper rendering? It might look like an improvement, but it seems to only "change" the problem. See the new screenshot attached - its after doing what you proposed. There are no longer artifacts around the character and so, but its still not right.
