Safari 13.1, which uses Adobe Flash(most current version in use, Xfinity is only stream that requires me to use Flash). If I open Safari, go to Xfinity Stream, and then open another tab in Safari, do anything etc, go back to stream, it refreshes after about 2 seconds with no input other that getting the fous on the streaming tab. Spoke with Apple support. Not a known issue. My Macbook Pro version of Catalina is 10.15.4. This worked as I would expect prior to an auto update on Catalina. As a course of troubleshooting, I tried on my new IMac, Catalina 10.15.3 with the exact procedure of, open Xfinity Stream, open another Safari tab, read whatever, go back to Xfinity Stream, no issue. Does not affect other streaming sites in Safari. Ok so i went a step further and loaded Firefox. No issue. Apple is making engineering aware. Has Xfinity seen this too? It is like it has to re-establish a connection with login info for a page/tab already running. Just an annoyance, and I want to use the native Safari over any other browser.
