If you set GDK_BACKEND=x11 the scrolling bug disappears, which is why I told that your hint normally would be an excellent idea. But I wanted to make sure that this bug is not closed because there is a workaround as using the workaround triggers other bugs in other places. Kind regards, Guner.

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. Cheers, Olly

That's not surprising - GTK2 doesn't support Wayland, so GTK2 apps will actually use X11 even if you're using Wayland. With GTK3 you can probably work around this by forcing X11, e.g.: env GDK_BACKEND=x11 /usr/bin/app Cheers, Olly

The two-finger scroll seems to be ignored instead. Ordinary gnome applications seem to work fine, instead. Also wxgtk3.0 applications that use gtk2 seem to work fine.
