This is a macOS10.13 issue, specific for some Intel GPU cards. Apple has fixed(partially) this issue inside macOS10.13.4 released build.
Following are the workaround for resolving this issue.
1) Update your mac machine to latest macOS10.13.4. Here, Apple has fixed this issue to some extent. You will face very less number of rendering issues.
2) Disable GPU preview and set display performance as typical.
Once you have updated to macOS10.13.4 .You might still face some rendering issues. Since, Apple has not fixed this issue completely.
Please switch off GPU rendering for these cases and report a separate post for tracking.

I've just bought a macbook pro 13" 2017 running 10.13.4
In all three programs, Illustrator, Photoshop and InDesign CS6, I'm having display issues with pixilated type, menus etc. The sole reason for buying this mac is design, which i can't do if a fix isn't found.
I cannot find where to switch off GPU rendering, is this only an option in CC?
