VLC plays 4K HEVC 10b Video only after fresh reboot

VLC Version 3.0.18 Vetinari

With today's nightly 3.0.19 and 4.0.0 the issue is reproducible.

I started the PC/iMac 18 days ago.

I'm running Bootcamp with Windows 10.

Meanwhile VLC plays only the audio track from 4K Videos until I reboot the System.

Only when I disable HW acceleration vlc --avcodec-hw=none <file or url> it shows the Video but the CPU load increases and also the System FAN rotation speed.

2K Videos are shown correctly.

Is there a way to restart the graphics engine or Direct3D11/DirectX?

                                 Hardware decoding
          This allows hardware decoding when available.
