Comment 73 for bug 1293384

Having the same problem on a late-2013 Macbook Retina Pro running Ubuntu 17.04 Zesty and previous versions.

Seem to have got a fix with:
1 CCSM General - OpenGL - 'uncheck the "Sync to VBlank" option' and
2 CCSM Desktop - Ubuntu Unity Plugin - check Enable Low Graphics Mode
