videos only play in kaffeine when opened the second time (first time green nonsense)

[Karl-Philipp Richter]

All videos that I want to play in `kaffeine` require to be opened two times because the first time almost the complete screen is in different greens allowing to guess what the image would look like. The second time the videos play fine reliably.
