if an underside pixel is "clear" then I want to sample the pixel at that position on the original layer instead of the "curl effect" pixel. There are two comments in the shader below where I check the alpha, and underside flags, and paint the color red as a debug test. The shader ...

In that case, you can ask Core Animation to preserve the aspect ratio for you using metalLayer.contentsGravity = kCAGravityResizeAspect and metalLayer.backgroundColor = CGColorGetConstantColor(kCGColorBlack);. Regardless, the macOS compositor efficiently sends the drawable directly to the display...
