I recently came upon a big problem while trying to highlight student errors in writing submissions in Canvas while using the Chrome browser on either a Macbook Pro laptop or an iMac desktop. When I highlight some text in yellow or orange, for example, the color completely covers the text, making it invisible. There is no tranparency in the highlighted areas. When I use Chrome on my Win 10 desktop at home, though, the problem is no longer there. Moreover, if I switch to Safari in Mac, the problem also disappears. Since Chrome is the browser I use the most, it would be nice to get this issue resolved as soon as possible. If anyone has any insights to this problem, please let me know. Thank you for your assistance.
