When I move an image in Lightroom I get rectangular areas, it seems that the screen does not refresh
I use a Mac Pro with 12 GB of RAM an Nvidia GetForce GT 120 512 mb and Snow Leopard
I have two displays : Eizo CG 243W 24 "and NEC 26"
Lightroom works in 64 bits
do you think it comes from Lightroom, the graphics card or Eizo?
thank you
