Color Management goes wrong, also Gamut warning has strange/wrong behavior

Open an image in sRGB with stronger red tones.
1. Now soft proof to sRGB (which should stay the same) and colors change a lot. That's weird.2. Close the soft proof feature and use the gamut warning in the latest PS version. Beside getting a gamut warning, red tones are shifting again. Why??? This is not simulating anything. Colors should stay the same, only clipped colors need to be shown in the warning color that is set in your settings.

I can confirm the behavior you are seeing. There have been numerous issues with both PS and LR Soft Proof with GPU acceleration enabled. You can fix this in PS by going to Preferences> Performance> Graphics Processor Settings> Advanced Settings and selecting Drawing Mode> Basic.

In the case of LR it appears disabling the GPU no longer fixes the issue, so something has changed. This is clearly a bug since out-of-gamut areas appear in sRGB image files with sRGB Soft Proof selection.

Are you using a wide-gamut monitor?

Yes I am, but that shouldn't make any difference since the monitor has been calibrated and a proper display profile assigned. Also LR Soft Proof used to work correctly so something has changed along the way to CC2015.12.

The question was meant for the OP, but you can't proof an sRGB document with sRGB on a wide gamut display.

I think you have it backwards. You can't soft proof using  Adobe RGB or other wide gamut color profile on a smaller gamut sRGB display, but you can do the opposite, correct?

Yes, I use a hardware calibrated wide gamut display.
