Netflix
Netflix performance issues are also reported in the thread "Netflix Performance & Issues", 4/10/19, and the suggestions in that thread might be helpful. Do a search for "Netflix" in the "Search this space" box on the Discussion page and you will quickly find that thread.
I searched boards relating to (1) Chromium (Linux) and (2) Chrome (Windows/Linux) this morning, checking for similar reported issues with either browser (both built on the Chromium/Blink/V8 base on which Edge Chromium is built).
I did not find anything addressing this specific issue, which suggests that neither Chromium users nor Chrome users are encountering the issue with any frequency. I have seen some threads discussing issues with Widevine DRM.
The most common suggestions for resolving Netflix streaming video issues on both browser platforms are: (1) reload/restart the browser; (2) check to see if the Netflix video runs properly in "icognito mode", and if it does, then completely clear the browser cache (history, cached images/files, hosted app data); (3) troubleshoot by disabling extensions, one by one, and checking to see if the problem resolves; and (4) specify a single DNS (apparently Netflix has some problems with DNS switching). I don't know if any of these suggestions will be helpful.
Along the lines of troubleshooting extensions, you might also troubleshoot by disabling PlayReady DRM, Widevine DRM, and PlayReady Experimental HEVC Decoding to check if any of those are creating the problem.
Please consider reporting this issue through the Feedback button in order to help the Edge team test/determine whether this issue is related to something in Verison Version 75.0.134.0.
