Fix crash when calling QWidget::grab() on a QOpenGLWidget
By avoiding unneeded nested QPainters.
Crash was:
ASSERT: "s" in file /data/sources/qt/qt5/qtbase/src/gui/painting/qpaintengine_raster.cpp, line 2239
s was nullptr because the inner QPainter had called updateState(0), which is then dereferenced by the outer QPainter.
Task-number: QTBUG-61036
