henno Really interesting test and conclusion, which basically supports what we have all felt for so many years now. The big question is, what exactly is going on and how can we approach Apple to push for a way to disable it. it's only a software switch - they could bury it in the OS somewhere and only provide it for those who need it. Temporal dithering or other subpixel rendering seem the most likely culprits.
When Apple were trying to diagnose my migraines they literally replaced ever part of my laptop, including the screen twice to try and find a panel which would work for me. I was assigned a senior technician to help with direct support, so it is possible to escalated pretty high in Apple's tech support.
But getting through to the actual devs...that's another story. What we need is someone on the inside who sees what we see.
