System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce GTX 1070 Ti/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 456.71

Blender Version
Broken: 2.93.0 Alpha, branch: master, commit date: 2021-03-14 22:11, hash: 070010e203
Worked: 2.93.0 Alpha, branch: master, commit date: 2021-03-03 22:32, hash: e4a55b46c4

Short description of error
The transparent shader setup looks like "white emission" in material and render preview, it also appears in the final render

Also some funky things going on with Ambient occlusion and bloom settings:
2021-03-15 11-18-33.mkv

In the older version the file is okay:

Exact steps for others to reproduce the error

Open attached .blend file
hit material preview or render preview
shader_test.blend

Perhaps this not a bug but a setting that I need to enable or change? But this is not documented anywhere (maybe related to this other issue: #86558 (Eevee render / preview artifact))

Thanks,

Lawrence

I cannot reproduce this on the current development versions of Blender.
Has this problem already been fixed?
Please try the latest daily build: https://builder.blender.org/download/
Go to File → Defaults → Load Factory Settings and then load your file to see if you still can reproduce this issue.
If the problem persists, please give us more clear instructions on how to reproduce it from scratch.

Hi,
I'm still getting the same problem with the latest built. But I have simplified the file to try to narrow things down a bit.
a) Default scene
b) Remove cube
c) Add UV sphere, subd 5
d) Add new node shader to cube
e) Add Glass shader to cube

What I get is the glass shader is glowing white like an emission shader:

In the older version (the working one), this is what I get ( assuming this is what it is supposed to be):

I'm attaching the file just in case:
glass_shader.blend

Thanks.

Can it be a graphics card issue then?
You have a Radeon I noticed.

It is quite possible, but this seems to be an isolated case. (Since I didn't find similar reports).
Perhaps it is related to this other problem that is already being investigated: #86604 (EEVEE roughness 0 results in bright white material)

Please double-check if the drivers are up to date.

You are right, it is related to #86604. This is a duplicate task then. I adjusted the roughness to 0.001 and it temporarily solved it.
We should just close this task then to avoid confusion.
Thanks for all the help, much appreciated.
