If you insist on conflating all your bugs into one big bug ball that just makes it more difficult to investigate, so it's less likely anyone can help you solve any of them. Ignoring other issues for now, does my suggestion actually address *THIS* bug? In other words, if run as above, does two-finger touchpad scrolling work? You haven't clearly said if it does or not, just that it doesn't solve your flicker problem (which I wouldn't expect it to). I can't easily test touchpad scrolling as I don't have a touchpad.
