The pattern flashes every time right after I pass through the grid. Is there a way to fix this? This is an EVEE render; I suspect this is somehow related to transparent node and I tried to change Bloom and other rendering settings, the issue seems to continue even in Cycles.
I tried to fix this with the second transparency node, but it still flashes lightly.

I looked at it with fresh eyes, looks like it really is fine. Thanks for taking a look.
