Cannot Create OpenGL Context etc under Android

The program worked under 10.2.3

Now I get an error when opening one particular screen.

Cannot create OpenGL context for eglMakeCurrent.

The Screen uses TColorPicker, TColorQuad and two TcolorBox

I moved the data module and only the absolute minimum screens to a new project -- which deploys to Android and works.

I added units that seem to support OpenGL -- but it wasn't helpful.. ANy other References to OpenGl cite similar messages -- but were not helpful.

Is this a known Bug???
