[Bug 511716] [NEW] Move pointer with keyboard is jerky

 

Public bug reported:

Binary package hint: xorg

I use the feature accessibility feature to move the mouse using the
keyboard's numpad keys.  This can be toggled on via the SHIFT + NUMLOCK
key.  The feature works, but the movement of the pointer on the screen
is very jerky when using the keyboard.  It seems like the cursor
position is only updated 3 or 4 times per second.  As a result, it is
sometimes hard to position the pointer because of the infrequent updates
of the position.  Also it looks terrible.  I would suggest that the
cursor position be updated at least 30 times per second, or more.
