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.Anonymous commented
After updating to the public release of 10.13.4 the graphics glitches seem to be significantly improved! I can now turn on GPU performance and use the program smoothly again. I recommend everyone having issues to update their machine and re-enable GPU performance.Anonymous commented
It's really annoying that I have to pay for software that doesn't function correctly. I disabled GPU Performance under preferences it fixed the display artifacts but the program is very laggy and slow. Hopefully it gets fixed soon because this is super annoying.
