The terminal now features smooth scrolling like in the editor. To test, enable "terminal.integrated.smoothScrolling": true and see if it acts like the editor.

Note that it's expected that all rows in the terminal are still "snapped" to the grid.

@Tyriar, should the terminal match the editor when it comes to page up/page down, as well as jumping between search results? Even though I have enabled the setting, reloaded the window, the experience for these two scenarios does not match the editor. Happy to get on a call and screen share if you want.

[Tyriar]

@lszomoru yes it should, that's a bug. Could you create an issue? I suppose ctrl/cmd+up/down is similar to jumping to definition so it should also animate scroll

Works on Linux!

The frame rate is a bit choppy since I'm connected through Remote Desktop, but I did feel the difference.

smoothScrolling.mov

I'm not able to notice a difference between it being true or false, but it doesn't mean it isn't working 😅 I'm happy to record a GIF with more or less movements if that would help?

@luabud when it's off, scrolling should "snap" immediately to the row, otherwise it would animate the scroll over 125ms. If you're using a scroll pad instead of a mouse it's much harder to notice as scroll pads have a feature called "ballistic scrolling" which does something similar already

@Tyriar ahh that makes sense, thank you! I was indeed using a scroll pad. I tested with the mouse now and was able to notice the difference.
