--- Comment #1 from Benjamin Xiao <ben.r.x...@gmail.com> --- For reference this is Wine Steam's desktop file: [Desktop Entry] Name=Steam Exec=env WINEPREFIX="/home/benxiao/.wine" wine C:\\\\windows\\\\command\\\\start.exe /Unix /home/benxiao/.wine/dosdevices/c:/ProgramData/Microsoft/Windows/Start\\ Menu/Programs/Steam/Steam.lnk Type=Application StartupNotify=true Path=/home/benxiao/.wine/dosdevices/c:/Program Files (x86)/Steam Icon=10B4_steam.0 StartupWMClass=steam.exe Here's the info from Window Rules for Wine Steam: Class: Wine (steam.exe Wine) Role: Type: Normal Window Title: Steam Machine: <hidden> Likewise here's native Steam's .desktop file: [Desktop Entry] Name=Steam Comment=Application for managing and playing games on Steam Exec=/usr/bin/steam %U Icon=steam Terminal=false Type=Application Categories=Network;FileTransfer;Game; MimeType=x-scheme-handler/steam; Actions=Store;Community;Library;Servers;Screenshots;News;Settings;BigPicture;Friends; And native Steam's window info: Class: Steam (Steam Steam) Role: Type: Unknown - will be treated as Normal Window Title: Steam Machine: What I am a bit confused over is why native Steam would match with Wine Steam's .desktop file when it specifies StartupWMClass=steam.exe? -- You are receiving this mail because: You are watching all bug changes.
