Short description of error
See what happened,dear.


I just linked an emission shader to mix-shader with a 100% transmissioned Principled BSDF, and raise some strength of the emission, then it happens. It will not back to normal while I switch the strength of emission down to 1.0...
Here is the source .blend file.

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

There are some (known) limitations for screen space reflections reflecting other surfaces that are reflective/refractive, see
https://docs.blender.org/manual/en/dev/render/eevee/screen_space_effects/reflections.html

However I am unsure if this can be considered as such?
(note that SSR will take the previous frame color into account so if for some reason we are running into a weird scenario, it might end up not being 'normal' again after dialing down the emission again...)

Anyways, would kindly ask @Clément Foucault (fclem) to have a look here (and confirming for now...)

I cannot reproduce this bug on my system. @Sdar (sdarpeng) Could you record a video of you reproducing the bug on your system? That would give a hint.

Make sure your drivers are up to date.

Also it would help us to know your system specifications.
