annotation and drawing markup tools: ovals and box not visible
I've been using the drawing tools to mark up a PDF, including the text hightlight, lines, rectangles, and ovals. They were working just fine but suddenly new rectangles and ovals remain invisible after drawing them. I can click in the area where they were placed and an outline box appears to let me edit their settings but they still remain invisible. Changing the properties including thickness, colour, fill, etc, none will change this behaviour. The existing rectangles and ovals are still visible but not new ones. I've tried on other documents and cannot create new ovals or rectangles. Lines, arrows and other annotation tools seem to be still working. I tried rebooting my pc and also the "Repair Installation" and still not fixed.
