+While there are apps and accessories to help dim blue light, and plenty of flicker-free monitors, temporal dithering can happen at the GPU level with no visible option to disable it (such as the case in Apple Silicon Macs).
 
 Stillcolor allows you to disable GPU/DCP-generated temporal dithering from user space, helping massively reduce eyestrain with little to no degradation in image quality.
 
 ## Caveats
-Note that while Stillcolor is 100% confirmed to remove GPU/DCP-generated temporal dithering, which is applied directly to the pixel framebuffer right before it's sent to the external/embedded display, the display panel's timing contoller (TCON) may still apply its own dithering/FRC to achieve advertised color bit depth. Whether or not Apple displays actively use TCON dithering in addition to DCP/GPU dithering is under investigation.

-- Make this app compatible macOS 11+
 - Create a foolproof and easy dithering test
 - Intel Macs?
 - iOS?
