Hello,

My sprites mysteriously disappears when i move around (both in game & in editor) depending on my camera angle with the sprites. Here is a screen to illustrate (moving from up to below the 0 grid) :

My 3 text sprites use the TranslucentUnlitSpriteMaterial and are at the same position on the y axis (blue background at 0, planet at 1, text at 2) but i have exactly the same behaviour if i change their y axis position.
This problem disappear if i change my material to MaskedUnlitSpriteMaterial.

Thank you for your help.

Hey Caracole -

I was able to reproduce this issue (TTP # 346557) and have reported it to our engineers for them to have a look at.

Thank You -
