By enabling NicosiaPaintingEngineThreaded instead of NicosiaPaintingEngineBasic which is the default implementation, we have seen that some frames are incomplete causing glitches on the screen. In fact, we are trying to upload buffers that have not finished processing. To avoid this problem, we must use the Nicosia::Buffer function waitUntilPaintingComplete() before each uploading.
