Unity Engine

I’m using unity editor version 2019.4.15f personal.

When i tried to run my project with latest editor version some stuff didn’t work good so i went back to this old original version of the editor. i’m not sure if this is the problem, maybe the problem has fixed already in later versions of the editor ?

I have a canvas and under it as child some ui texts that are my main menu texts.
For some reason after running the game few times the ui texts color changed to black.
The default the color i was setting was white but for some reason it’s changed to black.

I think quitting the unity editor and open the project again might fix it but it’s annoying because it’s not the first time it happens.

Then if i set the child image BG_UI off disable it then you can see that all the texts colors is black and not white.

And for example this ui text settings of the New Game UI Btn you can see the color is set to white but in the editor and runtime the color is black :

And now i saved the project in the editor clicked the saving option in the editor menu and the white color came back but it’s not a solution. this colors changes happens too many times.

Make sure no part of anything anywhere in your hierarchies is ever scale zero.

This means also not even just the Z component being zero… NOTHING can be zero scale.

Allowing the Z component of scale to be zero (easy to do if you use a new Vector3(x,y) in code without supplying 1 for Z), then you get black text and all manner of other UI and layout failures.
