Description Said Abou-Hallawa 2022-06-15 21:16:20 PDT

Sometimes CG fails to create GraphicsContext for some color-spaces. The conversion to sRGB will happen anyway when drawing the image to the destination GraphicsContext. So let's create ShareableBitmap with sRGB color-space when sending NativeImages to GPUProcess.

This sounds surprising. How do we support bigger color spaces then?

This seems to be a bug in one of the underlying frameworks.
