On every computer I've tried, Reshade's depth map gets distorted in SecondLife unless you mess with the window size/resolution and even still sometimes if you enable or disable the effects a few times it will become distorted.
SecondLife runs OpenGL
Computers I've tested include
i7 7700K, 1080ti, 32GB
i7 4700HQ, 770m + igpu, 8GB
i7 8750H, 1070, 8GB
