I think #GNOME #GTK / #LibAdwaita, #Tuba and #phosh are great and I want to use all of them even more than I already do. This is a respectful observation and I would love to be schooled about this.
My issue is on #LinuxMobile, I find scrolling really slow in LibAdwaita apps. So I used AI just to do an experiment. I created LibAdwaita styled components in Flutter and then replaced the Tuba interface with a Flutter UI. I found scrolling smoother / performance of the app way way better. Why?
@michaeldavies GTK4's GPU renderer is very inefficient, especially when it comes to blurs and shadows - and Adwaita loves blurred shadows. That said, I believe Tuba in particular easily gets CPU-bound, so there's likely some area for improvement within the application itself.
