Reflection "ghost" when using EEVEE Reflection Plane I'm trying to set up a nice looking partially reflecting glass plane in EEVEE. To test this, I just used a solidified plane, two Suzannes and a reflection plane.
What bothers me is the fact that the Suzanne nearest to the camera is reflected twice: Once seemingly correctly and a second time faintly and about half the expected size. 
What am I doing wrong?

Depending on what you consider to be the ghost reflection, you can use one of the following for the glass material:

Both use &quot;backfacing&quot; from the geometry node. To eliminate the ghost, we choose only one reflection (either back or front facing).
On left, the backface is reflective (as front face is transparent).
On right, the backface is transparent (and front is reflective).
0.25 is the alpha value.
