Hello Atari,
I’m using the libretro core, as I’m only interested in Retroarch for emulation in order to have everything unified under the same system (with the exception of Dolphin by now).
Besides, I think you cannot use shaders nor decorations in the standalone emulator as this is a retroarch’s feature.
This shader bug thing is happening since the beginning of the implementation of PS2 libretro core (v31 or v32 beta I think). On v33 beta, still happening.
I think this could be related with OpenGL/Vulkan version of the shaders, as PS2 core doesn’t work if you select Vulkan as graphics api. But just guessing.
