Button partially dissappears on Android using GLES2 in ui preview14, on Unity 2020.3.0f1

Hello,

I tested the UI toolkit runtime preview 14 on a rather old Android Samsung Galaxy S5 mini with Android 6.0
On this phone the UI looks broken, for example a button appears and dissapears when I click it.
On a newer phone which is capable of GLES3, this issue does not appear.

Possibly my settings are not correct, or this is a bug. Please help me :slight_smile:

I appended a screenshot of what it looks like in the Editor and a picture of how it looks like on the phone. Below that you will find my Unity Version and the list of used packages in the project.

I created a 2D project and included the packages for the ui toolkit runtime.

Unity Version: 2020.3.0f1

Update: Using 2021.2.0a8.1261 creating a fresh 2D project and using the built in ui toolkit this problem does not appear.

Hello! We have a fix for it (as you could see on 2021.2) and the next version of the package will also contain the fix. Thanks for reporting anyway!
