IMHO, there is a misunderstanding here, as far as I've understood, most of
applications don't have to take care of going to background and coming back
Reading all these and previous similar changes I was wondering why other
mobile platforms don't have this issue? If I'm not mistaken in no other
mobile platform the developer has to take into account if his/her

I see.. So if this pattern is more common then perhaps a different strategy is
in order. Thinking out loud:
One option we could implement is to have a hint on the canvas that it should be
retained. Meaning, when the application is hidden and the scene graph and the
GL context is invalidated, we
Yes, I did choose this way by the nature of my paint application.
Potentially recording all strokes etc. could consume also some amount of memory,
and maybe make the usage-experience tacky.
On charts etc, I also would redraw, and the data "is there".
I have another app where I need to implement t

Hi,
If you are not using Open
You are only affected if you use QtQuick in combination with OpenGL and the QSG
classes.
Raw OpenGL, SDL, etc is not affected.

Then these calls aren't available:
QQuickWindow::setPersistentSceneGraph(true);
QQuickWindow::setPersistentOpenGL(true);
The same for:

Hi,
If you are not using OpenGL directly or the Qt Quick scene graph's C++ API,
please ignore this mail.
Qt Quick and the scene graphs supports releasing its graphics resources when
the application is not rendering. This is not a feature we have been taking
advantage of so far, but as you can
