When enabling Forward Shading in a project while using the Lumen Global Illumination system, the shadows in the viewport begin to flicker and occassionally entire meshes may appear black. The lighting also seems overblown as well.
I tested this with Forward Shading disabled and did not encounter the issue. I also tested with Forward Shading enabled, but Lumen disabled and did not encounter the issue either, so it seems to be the combination of both rendering settings.
RESULT:
The shadows start to flicker
EXPECTED:
Forward Shading would not causing Flickering when using the Lumen GI system
