Hi everybody !
I’m facing to a weird problem with my UI image …
I’m doing a game for IOS, Android, Mac and Windows. All build are perfectly work except one… IOS.
My device is a Iphone 11 with IOS 14.2.
I’m using lastest Unity LTS 2019.4.16f ( I tried with new 2020 Beta and the problem still there) with URP
When I build for IOS and play the game , some UI image disappeared , or become invisible ( I don’t know really)
For info:
-I Have multiple canvas but there are all the same ( I just copy-past them to create a new one)
-All UI image have the same default material and are in the same atlas.( I tried to put different material and nothing change…)
- I have other image in the canvas where the problem appeared but none all of them are affected.
-I have textmesh pro in these image object and they are not affected ( So it’s not a disabling problem)
Here a screeshot of one of these image and his Canvas ( I don’t have any script that interact with this image or his canvas, It’s just a button)
Info 2 :
-When I touch where the button should be, The button work perfectly ! But invisible…
-If I remove Metal from Graphic API and add OpenGLES3/2 , the problem is gone on IOS, but it force to use gamma color and I need Linear Color so it’s not a good option…
-I had this problem with Textmeshpro too, but I solved it by creating a new font material preset , one for ui, and one for the wordl game, but here it haven’t solve my problem…
If someone can help me to resolve this i’ll really appreciate 
!
Have a nice day !
