Bug #: 30726 Summary: Key repeats itself after a "lag" Product: Wine Version: unspecified Platform: x86 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown AssignedTo: wine-bugs@winehq.org ReportedBy: pigeon@pigeond.net Classification: Unclassified
Sometimes the game is blocked for a little while (maybe when it is doing disk access, or busy, etc), which the screen (and the game) is frozen for maybe half a second.
If a key (e.g. the "a" key) was being pressed before this block, then after the block, if you press any other keys, the "a" key will start repeating itself. And it seems the more you press, the more the "a" key will repeat itself.
The only way to "fix" this is to restart the game/wine.
Have been getting this problem with various wine versions (1.3, 1.4, 1.5), and with both World of Warcraft and Diablo 3.
