Describe the Bug
On Farming Simulator 17 (and probably other games...), a color bug inverts the colors. After investigation, it's the
B8G8R8A8Srgbformat that's causing the problem. I tried to fix it by inverting the colors ofB8G8R8A8Srgbin the8_8_8_8format, except that it also inverts the other format colors. On my fork you can see the changes made. Feel free to use them as inspiration for a fix.Master:

Other games have this same 'problem' where the Format8_8_8_8 colors are inverted, such as CUSA08253 and CUSA03455.
Inverting them is not correct because in other games they are correct.
Maybe some shader is causing this
@squidbus commented on GitHub (Mar 16, 2025):
It's most likely related to output swizzle, but there are complications relating to how swizzle interacts with blending that are standing in the way of properly fixing this.

On my end I faced this issue in GoW3 after #1869 broke text in menu, but your fork will invert all 8_8_8_8 formats not only Srgb, made a little adddition to your fork code, seems to have fine colors in GoW3 and other games too

Knack also appears to have this bug.

Can someone with this issue check with this build: https://github.com/squidbus/shadPS4/actions/runs/14770906700
Not sure about Knack but I think this would help with the other games assuming it doesn’t add any other issues.
@StevenMiller123 commented on GitHub (May 1, 2025):
Doesn't seem to improve colors in Digimon World: Next Order, though I'm also not sure if the color issues in this game are related to B8G8R8A8Srgb.

The patch provided here actually confuses me a bit, you’re reversing both the format and swizzle to BGRA which should just cancel out
@Randomuser8219 commented on GitHub (May 1, 2025):
The new build by squidbus didn't fix Knack

Seems to be fixed by above from testing, we can track Knack issue here: https://github.com/shadps4-emu/shadPS4/issues/2843
