Cursor lag when moving the cursor over PDF documents open in Safari since installing Mountain Lion and updating to latest Safari

Cursor lags enough to make it tricky to keep track of when trying to highlight parts of the document.


Mildly irritating.


2 work-arounds:

  1. Opening the PDF in Preview instead
  2. Manually switching to the discrete nVidia graphics (instead of integrated Intel graphics) = no cursor lag in Safari


Am I alone on this one?
