Bug ID: 37995
           Summary: Mouse jittering when steam overlay is enabled
           Product: Wine
           Version: 1.7.33
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

      Distribution: ---

When the steam-overlay is enabled, the mouse in Skyrim, Fallout New Vegas, and
Fallout 3 jitters in the 3d view. The visible cursor movement in menus is
totally smooth and normal.

When moving the head, the view center jumps around slightly, but only when
moving the mouse. The game is playable, these micro-jumps are really annoying.

It feels as if the mouse does not provide consistent but rather noisy and jumpy
data about the coordinates or the mouse underground is bad (dirt, reflections).

This was my guess for a long time, but I just figured out the problem does not
occur when the overlay is disabled.

Maybe this is related to #32913.
