On Android with Honor 6 grabToImage() takes noise image

QEventLoop loop;
QSharedPointer<QQuickItemGrabResult> grabResult = itemInQml->grabToImage(); loop.connect(grabResult.data(), SIGNAL(ready()), &loop, SLOT(quit()));
loop.exec();
loop.exit();

QImage qi = grabResult.data()->image();
qi.save("Test.jpg");

On LG G2 / Android 5.1 and Win10 it works correctly. On Honor 6 / Android 6 the result is a randomly noise image, The format shows Format_RGBA8888_Premultiplied.

Similar to QTBUG-59303.
