EA APP starts and seems to work with Proton 8.0-2 at first. But after downloading a game from the library, it's not possible to run it. As I remember, I required Experimental to install EA APP as external program at first and needed to switch to 8.0-2 afterwards.
When switching to Proton 7.0-6 (which seems to be the only working stable version for Ubisoft games), the APP window UI will render as black (with invisible buttons clickable), which is useless, as is 8.0-2 ultimately, since EA games like Crysis 3 won't start with it.
After switching back to 8.0-2, the downloaded and "installed" EA game is then vanished from EA APP, and stays so, even after switching back to 8.0-2.
In addition, the Steam client will grey out and block the Proton version drop down box, once EA APP (or any externally installed game/program for that matter) was launched, until Steam was completely closed and restarted.
