Video Playback of multiple Videos freezes Unity Editor?

Recently i tried to display multiple videos with the new video player component. When I switch to play mode it looks fine at first, but the entire editor will freeze soon afterwards (1-5 minutes after pressing Play) and needs to be shutdown with the task manager.
There is however, nothing fancy going on. Just six gameobjects with attached RawImages and Video Player components. The videos themselves are quite small(resolution-wise) so the overall bandwidth requirement of all six videos should be well below of a 1080p HD video. I attached the example project to this post, which shows the details for the test.
Is there anybody who observed the same problem? And is there any way to work around this? So far I tried to use the transcode option to h.264 and to update my Geforce drivers to the latest version. But both didn't solve the problem for me.

Used Configuration: Windows 10, Unity 2017.2.0f3, Geforce 1070

 

Just to let everybody know who has the same problem. I filed a bug report and it seems to be offical now that there is problem with Unity. You can lookup the details here https://issuetracker.unity3d.com/is...multiple-videos-dot-webm-freezes-unity-editor
