Occasional sudden brightness changes are a side-effect of the way it works and cannot be completely removed without hurting performance or removing sharp shadows from light sources. To do the latter, disable `Per-Pixel Lighting` in the `Rethinking Voxels Settings`. This shader is developed on Iris, using an AMD graphics card on linux, and it is also tested on an NVidia graphics card on linux. While it usually works on other platforms, bugs that appear only there are not caught by my testing and hence they take lo...
