Case study

1) We have some initial form which is a target control for GLPlayer (see Form Based GL Application template).

__player = new Tizen::Graphics::Opengl::GlPlayer;
__player->Construct(Tizen::Graphics::Opengl::EGL_CONTEXT_CLIENT_VERSION_2_X, pMainForm);

2) We add new form which becomes active form of the app frame.

Frame* pFrame = UiApp::GetInstance()->GetAppFrame()->GetFrame();
Form* pForm = new Form();
r = pForm->Construct(FORM_STYLE_NORMAL);
pFrame->AddControl(pForm);

3) New form contains the Web control displaying html page with input fields.

Web* pWeb = new Web();
pWeb->Construct(pForm->GetClientAreaBounds());
pForm->AddControl(pWeb);

4) After switching back to the initial form some random textures disappear. Seems something bad hapenned to gl context.

pFrame->SetCurrentForm(pMainForm);
pFrame->Invalidate(true);

What is the reason? Is it a kind of low memory issue or something else? App doesn’t receive any low memory events.

remark: I noticed that this bug mostly happens after typing something in the html input field in the second form.
