Screen Space Reflections broken on Linux?

Screen space reflections (using the Post Processing package from the package manager) have always been broken for me on Linux (Unity2019 & 2020 on Ubuntu19 & 20).
Instead of showing actual reflections from a correct angle, it shows an offset duplicate of the real geometry, as well as another copy right behind it, noticeable as a "glowing outline" around brighter objects.
Is this a known bug of the Linux Editor? Is anybody else experiencing this issue? Are there any possible solutions to this problem?
