Hello,

this is most likely caused by “Adaptivity” (This switch is located in “Development/Experimental stuff” in render settings - To see this tab, you need to allow Preferences>Corona>Enable devel/debug mode first).

You can read up on adaptivity more in https://support.corona-renderer.com/hc/en-us/articles/4402704757009-What-is-adaptivity-

For a scene like yours, it may be valuable to turn off adaptivity.

Thanks,
Jan
