Bug ID: 56098
           Summary: Mouse pointer lags when using two monitors in X11
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown

If you have two monitors connected, the mouse pointer lags and things become
sluggish for a while when opening programs through wine.
But once the program has loaded, it works fine.

The thing is though, if I UNPLUG the display cable (not the power cable) from
the secondary monitor, the mouse pointer lag disappears. Disabling the
secondary monitor is not enough nor is turning it off.

I'm not sure if it's wine or if it's an Nvidia bug. I tried different versions
of both Wine and GPU drivers but I always come to the conclusion that that
unplugging the display cable from the secondary monitor fixes everything.

It does not happen on wayland, just X11.
