Photoshop CC 2018 error with canvas display

[heechulj30172433]

The canvas constantly breaks like this while I'm working. The error remains still unless I go back to the desktop and come back to the Photoshop.

This doesn't happen when I'm using Photoshop CC 2017, but since it's pretty slow I have no option than using a 2018 version.

Please help me to figure out this weird error
