i encountered some issues with an animation. Out of 101 frames 46 look like the attached one. They get seemingly inverse coloured square artifacts all over. The attached one is the worst of them all, some are artifacted to a lesser degree or more monochromatic. In final render output the squares on most images get black, but in the viewport or render preview they are always colourful like shown.
up on request i could share the .ksp - but i as well opened a support ticked where i attached the .ksp for the luxion team
there are 5 physical light sources: an area light + a spotlight, both animated with a fade curve and colour fade. The Spotlights poition is animated as well. And 3 area lights static in the light. Turning all animations off provided the same results.
its rendered without caustics, in interior mode. 30 samples with denoise at .4 . The Artifacts get worse with more samples though. And they do seem to not appear in product mode.

ive sent you the file.
the fix deleting the Settings.xml worked the first time for about 10 frames, the secodn time it didnt work at all: even the viewport got artifacts.
thanks nonetheless :)
I reported this april 9.th, 3 months ago. For a big this serious I find it unacceptable that it has not been fixed.
bug, not big...
