Visual Artifacts and Behavior Discrepancies with Radial Progress Bar

[michael-hawker]

Was just playing with the updated XAML Controls Gallery, noticed some issues with the new determinate Progress Ring:

• Value of 50 isn't half of the circle:
  

• Values aren't determinate. Setting a value doesn't result in the same behavior all the time:
  
  

• The above means that in many cases there is no visual increment when incrementing between numbers (every value should show a discrete amount of the arc when the control is large enough on screen):
  
  

(I saw it go for 3-4 steps without moving, and then this seemed to cause a large jump between 99 and 100 at times.)

• The ring isn't completely filled at 100 (you can still see the end caps of the segment):

I think that's a dupe of #3787.

Indeed, thank you @chingucoding. Closing this issue as a dupe.

Ah, sorry I didn't see that one had already been filed based on my comment! 🤦‍♂️
