            Bug ID: 45518
           Summary: Empire Earth GOG: Mouse lags since update to 3.13
           Product: Wine
           Version: 3.13
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org

Since updating Wine from 3.11 to 3.13, the mouse pointer is extremely laggy in
Empire Earth (GOG edition), in both the menus and the actual game play (which I
barely managed to with that amount of lag). All one has to do to reproduce this
is launch the game and move the mouse in the main menu

I have been playing the game for a few months now on OpenSUSE Leap 42.3 (x86,
64bit), using bumblebee (so I called "optirun wine "EE-AOC.exe"). Everything
worked totally fine, the only thing I had done in the very beginning to play
with EE's graphics settings a bit. Since then I have not done anything that
could have caused mouse pointer problem.

To make sure that the problem is indeed caused by the Wine update, I tested the
following Wine versions:

Wine 2.0.1 - similar problems, though not entirely the same
Wine 3.9 - this is what I downgraded Wine to right now (because 3.11 is not
available anymore in my repos), here everything works fine
Wine 3.11 - this is the version that I used before 3.13 and everything was fine
here
Wine 3.13 - this is where I noticed the problem for the first time

In addition, the AppDB page of Empire Earth
(https://appdb.winehq.org/objectManager.php?sClass=version&iId=25242) describes
a similar-sounding problem for all Wine versions prior to 3.4 that the game was
tested with ("mouse slow").

I am aware of the very similar bug report
https://bugs.winehq.org/show_bug.cgi?id=13351 and maybe it's got something to
do with this, but I'm not sure that the lag I'm experiencing is exactly that
problem: The workaround mentioned there ('xinput') did not help me (as opposed
to the people in said report).

Judging by the above observations, my guess is that somewhere between 3.0 and
3.4 the problem has been fixed, but somewhere between 3.11 and 3.13 it has been
reintroduced.

The bug I mentioned above lists this link as a source of a demo version of EE:
