Background colour is pale yellow instead of white

Hello,

My PC did the recent windows 10 update, and coreldraw now has a pale yellow background, and the white colour also looks yellow.

I have checked my colour settings within coreldraw, and they all seem fine.- I have attached a photograph to show ./resized-image/__size/320x240/__key/communityserver-discussions-components-files/810/Settings.PNG

Thanks in advance for your help.
