Above is a gif of this rather strange occurrence .
A link to my file in Google Drive: here
There are some rather strange effects I can't quite understand as to why it happens. For one, if the object is not selected, it appears red and black as expected. The moment it is selected however, any form of movement will result in the screen blowing up with exceptionally high amounts of bloom. Which is strange really, because diffuse and transparency each have 0 emission whatsoever, so I am not sure what causes the bloom here
Setting opacity to alpha blend also leads to very strange effects. The rod turns into a mix of blue and red. Red is expected, after all the diffuse shader is red, but the blue? There is 0 blue in my shader network, how did it end up here?
Is there a way to logically reason as to what is causing these two issues? While I find the effect intriguing, I would like to know WHY it happens.
