Summary: Shadows and selection circles z-fight in World of Warcraft Product: Wine Version: 1.1.23 Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: trivial Priority: P3 Component: directx-d3d AssignedTo: wine-bugs@winehq.org ReportedBy: eiffel56@gmail.com
The lowest-setting shadows and selection circles in World of Warcraft do z-fight with the ground. This is not a regression afaik, at least I haven't seen an other behaviour yet.
As I was testing if the patch attached to Bug #14174(http://bugs.winehq.org/show_bug.cgi?id=14174) causes problems in other games, I noticed that the same patch does almost fix the problem in World of Warcraft. I modified it a bit so it entirely fixes that z-fighting, but now it doesn't fix the bug mentioned in report #14174.
As I don't really understand why its causing that, someone with enough knowledge should investigate in it. I will attach the modified patch, allowing to render lowest-settings shadows and selection circles correctly.
