I have a Chromebook Pixel Slate and whenever i try to launch a game using either the Stadia PWA or the Chrome browser, the game launches but the screen is blank. Occasionally i will see something, but it looks like the screen is "tearing" and no inputs will work except holding the escape key to close the game.
I've tried uninstalling the PWA, resetting permissions, etc. but nothing works. Do anyone have any ideas?
I've not seen this on my Slate (yet). Do you have any flags or extensions enabled? You might try disabling all of those first to see if that makes any difference. Or, better yet, you could reset all your browsing settings to default, which would help to start with a "known-good" configuration.
