Fix flickering (black frames) of wayland clients on NVIDIA
When using the threaded render loop rendering the texture we acquired
from the eglstream is done in a different thread. This rendering needs
to be finished before the next acquire call for the eglstream is done
otherwise we might end up rendering a broken (black) frame and see
the client flicker.
To fix this, make sure to send the frame callbacks after the rendering
was completed and not before the rendering starts.
