Corona bitmap in Corona 10 in 3ds max 2024 the ticker for gamma and automatic will not change. The bitmap changes but the ticker is not. So if you want to change from SRGB to linear and back, you have to guess which Corona is sticking with. Its not buggy in 3ds max default bitmap node, only in corona bitmaps.
TO reproduce, just add a corona bitmap to gamma 1 and then open it a second time, you will see it has reverted back to automatic despite not changing the image to automatic.
