Hi d954mas, If the background the letter and the cost are on same Z maybe is an math approx issue. Try moving background a little far (0.1) or the letter and cost a little near. Maybe will work 🙂 ---

No. It have a big z differences. Looks like it depends on go position. If i move letter cost to (0,0,z) it will work. ---

Is your camera orthographic? Try switching to a perspective camera like with rendercam? I remember facing this problem in the past but I don’t remember the solution. 😕 Is depth test enabled in your render script? > [@The label component blink when rotation GO over Y axes (SOLVED)](https://forum.defold.com/t/the-label-component-blink-when-rotation-go-over-y-axes-solved/9311/4): > > I think it has to do with the sorting inside the engine in combination that you probably don’t have depth test enabled in your render script. I put together a super quick example, I’ll attach the project as a zip. Let me know if you have any questions!

Do you use scale\_along\_z = true in the collection? ---
