Short description of error
F-Curve sliders won't update during animation playback if the mouse cursor is outside the F-Curve's left panel when you trigger the action(Alt A or pressing the "Play animation" button in the Timeline). The values will only update if and while you point the cursor over the sliders and keep moving the cursor there.

Exact steps for others to reproduce the error
Press Alt A while the mouse cursor is outside the F-Curve's left panel; or press the "Play animation" button on the Timeline's header.
After that, also, move the cursor over the sliders and keep moving it there, the values will only update while you do that.

If you press Alt A while the cursor IS on the left panel, the values will update properly.

I don't have permission to Edit the Task and add the .blend file, so I'm adding it here: f-curve_sliders_dont_update_bug.blend

This is a known glitch of current system, not considered a bug really (since values themselves are updated). We just want to avoid redrawing the whole UI each frame, saves some ressources for what’s really needs to be drawn.

Oh, I see. So, then, it's a Design issue.
It's still an issue, though. It's really annoying to have to remember to hover the cursor over the left panel when you want to see the sliders values during the animation. It gets in the way by making you think about this technical detail that has nothing to do with the animation you're doing or the little change you're checking in your animation.

So wouldn't it be useful to reopen and change the type from "Bug" to "Design", then? For a future fix/reference?

What about updating only while you have the cursor present in the F-Curves window, even after pressing playback? And then if you move the cursor off the F-Curves window, it stops updating; if you move it back, it updates again.
It would be less annoying because you could play and then hover the cursor there if you want to see the values updating. Now you playback and realize the values are not updating and then you have to stop the animation, hover the cursor over the F-Curves window and then play it again.
It's really irritating after a while and kills time.

I've just noticed that this issue also happens with sliders in other panels. It seems to be a global behavior regarding sliders. If I play the animation while the mouse cursor is outside panels that has sliders, those sliders won't "update".

I've tested Branch: testbuild Hash: 3d4f540 and it doesn't happen in the F-Curves anymore(Apparently because of the commit you guys did) but it still happens in other panels.

Why can't I edit the task, being the author? I think it'd be appropriate to change the title now that it doesn't seem to be specific to the F-Curves Window.

For other editors, you have to enable them in the 'Playback' menu of the Timeline editor… No bug here.
