I use acrobat reader X v 10.1.1 on Mac OS X 10.6.8 with dual display. External monitor is rotated 270 degree. On this setup, a document containing perfect circle showed properly on internal display, but it will be distorted when Acrobat Reader window dragged to second display, then the page refreshed (can be done by change zoom level or maximizing window). Is this a known bug?
PS: I haven't found any other way to report bug. Please let me know the proper one if it is not here.
Thank you.
