Corel Draw 2018 refreshing issue while text editing


I have problem both on Win 10 and 8.1  with similar specification PCs. 

Intel Core i5 - 7500 3.4GHZ x64

16GB Ram

Intel HD Graphics 630

When I am editing text, sometimes it dobule the lines after enter (attachment) or do not make any changes in text until I refresh view with CTRL+W or zoom out or zoom in.

It slow down work very much and it's a big issue for me. When I was using CorelDraw x5 eveything works just fine.

Thank you for any help
