[Development] [QML] Avoiding graphics flicker in Quick2

[Denis Shienkov]

UPD: Now, I have running the qopenglwindow example application with
QT_QPA_EGLFS_FORCE888=1 and see that flickering artifacts occurred
sometimes.
It is an interest moment, that without QT_QPA_EGLFS_FORCE888, the OpenGL
draws the rectangle more slowly.
