Yes, the title. Icon shows up fine when it's located on air / dojo or toris from distance. However, when I close view toris and it gets into those textures, it appears invisible, which is not good, because all the other stuff shows up and it showing up is more cool.

I'm using 4.41 and this problem seems not good at all for me as a icon owner

I don't think that is much of a problem since people don't tend to watch fights from inside tori/ukes joints. If you really want it fixed, report it as a bug.
