A closeup of the cursors in slow-motion is provided below for forensic analysis.ĭiving deeper into the guts of cursor files, its revealed the Windows 7 cursor is actually designed to display each frame for 3 “ jiffies” (1/60 of a second) whereas the Vista cursor displays each frame for 2 jiffies. What’s most bizarre is although the style of the cursor is not new to Windows 7, the same cursor in Windows Vista actually does not exhibit the same phenomenon. If you’d like to test the phenomenon for yourself, simply hover over this paragraph which overrides the cursor to display the busy cursor via CSS.
