Actually I believe these problems are fairly common. I&#x27;ve seen them mentioned before and I experience them myself. I think it has to do with integrated vs discrete graphics in Mac laptops.<p>Disabling transparency in the accessibility options used to fix it, but it doesn&#x27;t anymore.<p>I&#x27;m very much hoping that Apple will include this functionality in the next major release of OS X as f.lux has historically had trouble keeping up with OS and hardware updates.
