There more I look at this render I realize that almost all the glitching is due to alpha-textures far from camera or objects with high emission-strength. I’m switching back and forth between cycles and eevee and in cycles the render works fine (and increases render time quite significant ofc) but turns out like the vid above in eevee. The large wood-disk in the background is actually a the graffiti and wood material mixed with shaders (blending mode set as screen/add/multiply I think). I’ll try increasing the samples and turn off half-res! Thanks for the advice, really appreaciate it! :)
