I am developing an application that uses a QOpenGLWidget and that would
greatly benefit from grabbing offscreen content.
I tried implementing grabbing but had no success but thats another story.
The new features of the upcoming Qt 5.10 mention:
QOpenGLWidget is now usable for rendering and reading back (grabbing)
Can anyone elaborate on why this is currently not possible using Qt 5.9 and
what changed in Qt 5.10?
Are there any workarounds in 5.9?
