Hello Jasperidone. Sorry for the late reply.
I see the issue: -Behind Pixzels is working a kind of a voxel engine but with single-sided coloured cubes and other things to get the most precise approach for a pixelart outcome... In your case when they are slopes with different colours cubes, the cubes display the colours of each side and create this artifacts. Im working on some ideas to apprach this cases in a intuitive way for the user.
Many thanks for your feedback.
