Android, Text / Font renders as Squares

Question

When I try sharing an image through my program, the share menu sometimes comes out looking like this.

Some Notes:

1) It doesn't seem to occur on the first run, but only after I have paused the application and gone back in.

2) My app uses OpenGL extensively. It is possible I am changing a shared setting, then not returning the value back to the original.

3) Everything else in my application works fine.

4) I have tried removing all the calls that allow transparencies, and I am still having this problem.

Answer 1

I have this problem too. I am using a GLES 2.0 context, the only way I have been able to get rid of this... (it's going to sound weird) is by NOT calling

GLES20.glDeleteTextures ( hTextures.length, hTextures, 0 );

It wasn't happening before I started clearing up my textures, and it hasn't happened again since removing it. I have no idea why that would be though?

I'm also not sure of the ramifications of not releasing my textures.

If anyone can shed light on the matter, that'd be great, there's a few versions of questions floating around. Appears it's a problem in Unity for android and everything.
