Created attachment 59055 [details] Patch for wine 2.15-staging
Old fashioned diff patch. Apply by calling "patch -p1 < PATCHFILE" in the wine staging 2.15 source folder after staging patches have been applied.
Does this patch fix all the issues? Please note that patches can be submitted at https://dev.wine-staging.com/ for review / inclusion to Wine Staging. A plain diff is not sufficient though because it lacks author information (Wine requires the use of your real name for all contribution). The easiest way to do that is commit your changes with (git commit -a -m "d3d11: ..."), and then use "git format-patch --keep-subject".
