Subject: in fgWarpMouse() we need to flush all mouse motion events before we can set
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=8e8b2bba04107924cf4b1c80e0604e7f9db9457b;p=flightgear.git

in fgWarpMouse() we need to flush all mouse motion events before we can set
the mouse pointer to a new position. Otherwise it can happen that the new
position is first set, but then come a few still unprocessed events for the
old position. This makes ugly jumps in mouse view mode.
