IPR refresh often at change of tonemappng paramaters

[Beck]

Hello Maru

I tried Corona 13 and it's the same. It also was in corona 12.
@ John: If i delete the camera tag, i lose the corona tonemapping controls, for example no more DOF settings...
One trick is to delete the white balance in the tonemapping controls, then it works. But if i i check bloom and glare, IR refreshes again.
