System Information
Linux Mint 20.1 Cinnamon 64-bit
3400G (iGPU)

Blender Version
Broken: 2.93.0 Alpha, d25ab68cf4, and 53b82efed6
Worked: 2.92.0 Release, and 2.93.0 Alpha e4a55b46c4

Short description of error
Refraction Depth > 0 no longer seems possible, unless using high levels of roughness.
Refraction Depth = 0 still provides an almost identical result.

In case helpful, regression seems to have appeared in the last few days (recent EEVEE refactoring?).

Exact steps for others to reproduce the error
Open the following .blend file in both 2.92.0 Release and recent 2.93.0 Alpha and compare results.
EEVEE SSR Refraction Depth regression.blend

2.92.0

2.93.0

Forgot to say...
Thank you @fclem, Your coding skills are greatly admired and appreciated.

2021-03-17 update:
Was fixed in 2.93 Alpha 1f8d27a191, regressed again in be51d671b5, and de06cb8559

Try either the above .blend or the following...
EEVEE SSR Refraction Depth regression test 2.blend

As per @lichtwerk findings (thank you for your tests and feedback!), try zooming in and out using the mouse wheel. Changing camera focal length (FL) also highlights the issue.

Camera FL 25mm

Camera FL 50mm

Camera FL 75mm

Camera FL 150mm

Thank you.
