I've got a strange issue with cove/under cabinet lighting. I'm getting these odd flickers that seem very specific square or rectangle shapes.
There's no co-planar surfaces.
There's no architecture/objects past the face of the affected walls. In other words, the squares showing up aren't related to anything beyond the wall.
This happens with both IES or standard Enscape lights.
I'm running 2.6.0 11215.
Here's a video showing the issue. Starts happening at around the 15sec mark.
