Subject: st/nine: skip position checks in SetCursorPosition()
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8b13aac9666951bade6ac5fff9eb7c45a7d2748a;p=mesa.git

st/nine: skip position checks in SetCursorPosition()

For HW cursors, "cursor.pos" doesn't hold the current position of the
pointer, just the position of the last call to SetCursorPosition().

Skip the check against stale values and bump the d3dadapter9 drm version
to expose this change of behaviour.
