[3ddesktop-dev] Re: gotoright, gotoleft not always exiting

The CPU spike is most likely caused by the autoacquire feature that is
turned on now by default.  At a specifiable interval the current desktop
is acquired (screenshot, scaled, converted to texture and bound).  The 
purpose of this is to maintain updated screen representations so there is 
no inconsistency between what you see in 3ddesktop and whats on your screen. 
It generally works pretty well - but there is a cost and it can really 
show up on slow systems.  By default this is done every two seconds.  At 
what interval do you see the CPU spike?

You can turn off the autoacquire by setting it to zero in 3ddesktop.conf
