Worked: version: 3.0.0 Alpha, branch: cycles-x

If it's working in the Cycles-X branch, then it will be fixed once the Cycles-X branch is merged into master.

Just to make sure. It works in the cycles-x branch but not in master?

If you wish to "fix" this issue for normal Cycles, then you need to select the object that's emitting light (blanc) and stop it from being visible to the "shadow catcher" object. This can be done with various methods (Ray visibility, Node tree, View layer compositing, just to name a few.)

@ThomasDinges , not sure about the Cycles-X build but it's showing the same results on older versions:

2.83.17	2.92	3.0.0
