Short description of error
When you use a reflection plane in Eevee, it seems to glitch when you're up close and also fades the edges of the viewport / camera both in viewport and final renders. This has been around ever since 2.80 but I never actually got around to reporting it
Exact steps for others to reproduce the error
Open the file attached and get close to the reflection plane while in rendered mode and then move around, it glitches + fades the edges of the view. This can be reproduced in earlier version of Blender / Eevee as well

I am not 100% certain but this looks like it's settings in the plane / camera to do with clipping distances
I've tried messing with those settings but it still glitches / fades

Actually I was just preparing to report this issue. This happens when using a reflection plane while also having screen space reflections enabled. The problem disappears if screen space reflections are disabled.
One workaround I found is increasing the camera's "Clip start" distance. In my case it happened with the default clip start of 0.1, but disappeared when it was increased to 0.5.
I prepared a test scene to demo the issue: blender_2.8_eevee_reflection_glitches1.blend
Procedure to verify:
While this workaround can get rid of the glitches, that clip start distance equals 50 cm when using metric scale, which is too large for many scenes and would require manually animating the clip start value to prevent the camera from "eating" objects.
@Takuya Thank you for that, yeah this workaround does work but is very finicky as you stated. Hopefully we can get this resolved soon : )

Changed status from 'Needs Triage' to: 'Confirmed'
Can confirm, that issue goes away when I disable screen space reflections.
