I recently ran in to these bumps with Gnome on a new Thinkpad Carbon X1 and the 2560x1440 screen. I love Gnome but Firefox in particular was unusable and it wasn’t the only app with issues. I begrudgingly installed Cinnamon and things are better. But I prefer gnome. Glad to see I can update my Firefox on gnome to this. I can switch back any time so maybe that will make gnome usable for me.
