There’s an incompatibility between Glared and the Flared function to “Force Eevee on a New Layer”.

When the “Force Eevee on a New Layer” function is activated from Flared and Glared is active, the preview in the viewport is not correct. At the moment we have no solutions to the problem. This is due to the fact that some nodes of the Compositor are not interpreted correctly by Blender 3.5’s Realtime Compositor. We hope that Blender will fix this problem soon.
