Bitmovin playing DRM content in WEBGL world

we are creating a metaverse solution for our customers using HUBS (mozilla) as platform

and we are using the Bitmovin as player for VOD and LIVE streams

the idea was to use and play our PROTECTED contents in 3D world

what’s happening is that all the DRM protected content are invisible
(Widevine protection): we see only BLACK screen (with the audio running…)

I think that in some way the “screen grab/recording protection is kicking in” when the WEBGL is used

Do you have any idea or suggestion for this problem ?

thank you very much
