EditText does not display input. Entered text becomes visible only after hiding the keyboard

On the screen there are 8 editText. They go up up in order. After transferring the project to another computer, where the latest version of Android Studio is installed, the last two editText has ceased to be displayed when entering. Before transferring to another PC, everything worked fine and there was no problem. I did not change the code in any way.

On the cropped screenshot, it can be seen that the input occurs, but as if under EditText, and the text itself can be seen only after folding the keyboard or switch to another EditText field.

The application has a “dark theme”, but this problem is not related to the change of colors.

Found a solution! The problem was in the line from Manifesta Android: hardwareaccelerated = "false"
As she influenced it, I am without a concept. To be honest, he himself would not refuse the explanations of those who understand.
