I'm trying to eliminate the "bouncing" or flickering reflection of an animated object rendered using EEVEE. I have a simple text object on a semi-reflective surface (specular 1.0, roughness 0.25) and screen space reflections enabled. When the camera is motionless, the reflection appears fine, but once the camera begins to move even slightly, the reflections begin to bounce and jitter as seen in the clip below. I'm somewhat (erroneously?) confident this is something to do with EEVEE's screen space reflections. The bouncing disappears when I render in cycles.
So, what exactly is happening here? I have played with each screen space reflection setting, but none seem to eliminate the flicker. The Blender manual mentions using a reflection plane, but also mentions that you lose the effects of subsurface scattering, volumetrics, and screen space reflection/refraction, which is not desirable.
Maybe I've gone down the wrong rabbit hole, but other basic troubleshooting such as increasing samples doesn't have any effect. Of course, turning off screen space reflections eliminates the problem ...and the reflection, which isn't desired.
