Filled sheared rectangles in PDF documents exported from InDesign are rendered incorrectly in the Adobe Acrobat extension for Chrome, but displays as expected in other PDF readers [ Preview, Safari, Quickview, etc. ]. The sheared rectangles are displayed as a box of the fill colour with the outer bounds of the sheared shape. Adding a stroke suggests the sheared rectangle is preserved, but is not honoured by the fill.

Work around: Adding an additional anchor point, or rounding the corners, appears to correct this issue.
