Summary: When having updates (one or multiple) window response time lags severely Product: Wine Version: 0.9.12. Platform: PC OS/Version: Linux Status: UNCONFIRMED Severity: enhancement Priority: P4 Component: wine-ipc AssignedTo: wine-bugs@winehq.org ReportedBy: ryanbach@adelphia.net
Where there is a Steam update (sorry I don't have logs) and I have set multiple items to "Always keep this game up to date" (right click the item, Properties -> Updates) then it lags the window in equivalence to number that are set to do so.
In the best case it is just a small annoyance and little time is lost, usually it just lags the window response time and at the worst the user could think that it is frozen because the window doesn't refresh at all and shows a mouse "trail" and severely impairs the update time in a negative manner.
