As the title says and screenshots show, I'm facing two issues with Edge Insider Dev channel (79.0.294.1), both related to Prime Video streaming service:
1) I cannot get Edge Insider to stream videos at 1080p resolution. This is not a recent issue, I noticed this problem on earlier Beta and Dev builds, back in May or June, when I started using Edge Insider.
2) screenshots on Prime Video when taken on Edge result in a black image. The first two screenshots were taken using Snipping Tool, and the last ones with Windows key+ Print Screen shortcut. This issue does not happen on YouTube, only on Amazon's streaming service, as far as I know.
Neither of those two issues happen on Chrome stable (77.0.3865.120).

please try turning these flags Enabled or Disabled and see if they change anything

The ultimate endorsement for any Digital Rights Management system is having certifications from Hollywood studios. They have millions of dollars on the line, when they make their content available via online streaming. Hollywood’s Digital Entertainment Content Ecosystem (DECE) endorses Playready’s DRM for streaming videos. Netflix and Amazon Instant Video use Playready for streaming on Edge.

@HotCakeX Fantastic, disabling both flags solved both issues, thanks a lot! I did it on an Edge Insider Beta build, but I'm sure the fix applies to Dev as well. I'm crossing my fingers and hoping Microsoft won't ever remove those two flags from the code.

@HotCakeX OK, so testing Dev and Canary builds, I concluded that disabling "Widevine DRM" flag fixes both issues. However, disabling "PlayReady DRM for Windows 10" blocks playback and makes the browser ask for Silverlight plugin, which is nonsense as it will be discontinued and HTML5 is the standard nowadays.
Once more, thanks for the help. I was afraid I would have to go back to using Chrome, but fortunately this is not the case because your suggestion promptly solved my problem :)

Great findings! hope developers see this and disable that flag by default until they have a fix for it.
You're welcome, anytime :)

I have been having an issue with the Amazon Prime videos flickering to black and almost instantly back to the video several times as the video buffers and it steps up the resolution until it gets to HD 1080p. I found the flags worked differently for me. Disabling PlayReady DRM for Windows 10 made the behavior go away. The Widevine DRM and the PlayReady Experimental HEVC Decoding flags made no difference Default, Disabled or Enabled. Disabling Widevine resulted in the Silverlight prompt.
