I'm using latest edge on debian (Version 110.0.1587.69 (Official build) (64-bit)) and connecting to AVD with my @microsoft email.
If I move the toggle to use the new client in preview, when I connect to my AVD instance (I use Europe vdektop) I see all the fonts and resolution blurry, not clear at all.
If I disable the new client, there is no blurry text anymore.
Let me know if you need more information
