--- Comment #22 from WineBuG <winebugs140 at gmail.com> ---
On macOS, when playing Captain Claw (https://archive.org/details/CaptainClaw)
and using the Mac Driver, there's something really strange going on that might
be related to this very bug: if you DISABLE v-sync via the registry key
"AllowVerticalSync" -- the animation speed is more or less correct (but not
quite smooth). This is really weird, taking into account that this bug is
basically about IGNORING V-SYNC by the game, and the fact that Windows users
are generally ADVISED TO ENABLE V-SYNC to fix Captain Claw's animation speed
and jumping issues (check out:
http://www.kapitanpazur.piasta.pl/en/support.html)!


You can achieve a similar effect when using X11 on macOS as well.
