White outlines around obejcts

[Elbucjio]

Hello, i’m doing something wrong. I got white lines around objects who stands against hdri background. Export open .exr fullflout 32 bit. Its ok, if I dont change backgrounds, but if I do, its messed up. Maybe some thougts or links where I can read about it. Thank you in advance.
