[macOS] macOS Screen Capture + Color Correction Effect Filter causes unintended color changes

[jcm93]

I think the issue is that certain colors in SCK captures are being treated as out of bounds or NaN when they reach the color correction filter. Colors that this happen to include ones well within the sRGB gamut. It looks like an issue with color processing internally, probably having something to do with SCK's captures being in the l10r pixel format.

Different colors are lost depending on the output pixel format set in Settings->Advanced, which further points to this being an issue either with how the color correction filter or OBS at large handles pixel formats internally.

Does this also occur in older versions of OBS Studio?

I have tested some other versions (28.0.0, 29.1.0, 29.1.3, 30.0.0, 30.0.2) and the 30.0.0 or later have the same issue.

I put an image as the background and the scene looks like this.

So it seems like there are some errors in the transparency processing.
