Eevee unable to render correctly without screen space reflections turned on.
Closed, ResolvedPublic


System Information
Operating system: Windows 10
Graphics card: Intel(R) HD Graphics 630

Blender Version
Broken: Blender 2.8 Beta Hash: 0f5b53ba4dc 2018-11-30.
Worked: (optional)

Short description of error
When rendering an image or entering rendered viewport with Eevee, on, the edges of any mesh have bright pixels and color distorted with random lines on the mesh.. When turning on screen space reflections, the distortion goes away in the viewport and in the final render. But turning it off again brings back the distortion in the final render.

Here are examples of the distortion. And here is an example when Screen Space Reflections is turned on

Exact steps for others to reproduce the error
Open startup file and enter render mode in viewport rendering with Eevee on and screen space reflections turned off.
Or render an image of the starting cube.

Have you tried updating your GPU drivers?
I'm suspecting that this is a driver bug.

Try updating to a later blender beta. The one you used is quite old by now.

If it still doesn't work try running blender with --debug-gpu and post what it outputs

Also try to run with the option --debug-gpu-force-workarounds

To everyone affected by this bug, please give us your system-info.txt so we can list your gpu/driver to use the fix. Thanks

Here's my system file as requested:

Something similar happened for me too, but I did not save the screenshot.

It's interesting. Last night I updated my system, my GPU driver was also updated. Now this bug is gone and I cannot reproduce it.
It seems that this is a driver bug or other bugs but not blender bug.

Closing as it seems that the latest drivers from intel fixes the problem.
