Bug #: 31846 Summary: World of Warcraft: graphical glitches with particle weather effects using D3D9 engine Product: Wine Version: 1.5.14 Platform: x86-64 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: directx-d3d AssignedTo: wine-bugs@winehq.org ReportedBy: thomas@ch.tudelft.nl Classification: Unclassified
Created attachment 41900 --> http://bugs.winehq.org/attachment.cgi?id=41900 Screenshot of blowing snow clouds using D3D9 engine
Due to a bug in Blizzard's OpenGL engine I switched to the D3D9 engine.
All works well except for the weather in, among others, Tanaris. During a sandstorm (sand clouds blowing towards the player) yellow, red and green pixels temporarily form on the screen, like sand blowing against the screen. The same is observed in the Valley of Emperors in Kun-Lai Summit, where there's snow clouds blowing towards the player - see also the attachments. The comparison with the OpenGL screenshot suggests that the pixels should actually be snowflakes.
This effect is affected by the particle density setting: decreasing the setting decreases the amount of pixels (and normally: the amount of snowflakes) and vice versa.
This bug has been observed using wine versions 1.5.13 and 1.5.14. No others versions were tested (using OpenGL before). Wine is set to windows XP mode using default library settings. msvcr80.dll is present in the directory of WoW.
