Hi. It is possible I have some material settings wrong, otherwise this is a rendering bug.
I have a sprite in the scene with partial transparency. In the sprite material I use AlphaCompositing blend mode as I this content is used in video production and alpha compositing must be correct. Behind the sprite there is a plane actor with partial transparency as well. Its material blending mode is Translucent. When I move the camera, the blending order sometimes changes. Here are the screenshots:
Correct blending
Wrong blending
As you can see in the second image the semi-transparent plane becomes blended in front of the image. This is wrong. And these flips happen dynamically when the camera is being moved along X axis back and forth with some amount of rotation around Z axis.
