ProgressRing determinate mode animation feels slow (~3 s) when initial Value is set to 100

[harvinders]

Describe the bug

I have a ListView that display status of various items. One important thing the item display's is the download percentage. I am using the determinate ProgressRing to display the percentage.

One issue I noticed is that when the item view is displayed, the animation takes close to 3 seconds to animate to the 100% value. Which feels very slow. This is especially true, when the initial value is already 100%.

Also, because of virtualisation the item view is reused with different view models and hence every time a new viewmodel is used that has a 100% for download status, the control is animated again (taking ~3 seconds). This happens when you scroll up and down enough to trigger the virtualisation.

Expected behavior

The animation should probably take less than a second.

Also, for virtualisation scenario ideally there should be no animation. I can understand that is going to be not possible unless animation is completely disabled for 100% (value is already 100% when the control is loaded/displayed).

Would it be possible to include Gif's of the animation in question?

@StephenLPeters Give me a day or so, I need a tool record it. Gaming bar is disabled for me.

PowerPoint has a good screen recording option if that is available to you.

The one drive video link is https://1drv.ms/v/s!AjCjW_y_qIQIga88B8RNM1f1r4Dsbg?e=L9IJPH

Many of the items have the download status of 100%. Notice when I first load the items. The progress ring takes time to reach 100%. I think the animation should not take that long.

Also at the very end of the video, when I scroll down and scroll up again I suspect the virtualisation kicks in and the progress ring again takes time to show the status of 100%.

Thanks, very helpful!

Really have a bad gut feeling about Lottie in places like this :)

As I mentioned in another repo - if this does not currently exist, then the ability to play animations in reverse, as well as with faster and slower speeds.

Question: Why did we move away from the spinning dots? Almost every progress ring uses that, even the Windows bootloader.
