--- Comment #38 from Nelson Chan nelson@nelsonchan.dyndns.org 2011-05-29 13:49:43 CDT --- confirm on wine 1.3.21 mouse jumping randomly in Day of Defeat:Source Arch Linux
strangely it was fine until a distro update for the same package (wine-1.3.21-1 -> wine-1.3.21-2) nothing special has changed (only added a dependency in package data, no build option changed)
more interestingly, i think back in 1.3.19 or 1.3.20, about the time gcc 4.6.0 released, i tried to compile wine with gcc 4.6, the bug occurs. (it was fine when i built it with gcc 4.5.x but i believe both wine-1.3.21-1 and 1.3.21-2 of arch linux are built with gcc 4.6 this cant explain why it works fine with 1.3.21-1
maybe some combination of other libraries contribute to the bug? maybe gcc?
