Android displays black rectangles instead of drawable images after opening openGL context -

i developing simple android app has few activities, say: a, b, c, , d. *activity a* splash screen. calls finish() when same info finishes loading. activity b displays info , few buttons activity c starts webview content accordingly button pressed in b activity d opens opengl context.

from activity go activity b., b c , c d.

problem face: drawables , progressbar display black rectangles after pressing back button coming activity d (activity starts opengl context). ideas should into?

adding android:hardwareaccelerated="false" <application> manifest workaround, not solve problem. opengl state , context preservation mentioned phil might play role here.
