Thanks Ben and Philip.
I have been working with Kathy on this issue. I haven’t heard from her yet to let her know what I found out, but wanted to give an update. It appears when you overlay a .png image (the pointer/needle) over top of a different .png image (the dial) it creates this issue. So I saved my image (the dial) as the .jpeg format (which it loses its transparent properties which kinda stinks, but oh well) and it looks exactly how I wanted it to look. The pointer is smooth and the “placeholder” as it rotates, is gone. The pointer blinks at random times but nothing like it was. I am satisfied with how it performs.
The downside for losing the .png image is I can’t maintain a “circular” image and when I decide to change the background color of the window, I will have to load my image program and recall the image and save the image with the same background that I just changed my display background to. Just extra steps, but I’m pretty happy that this looks pretty good. Maybe the developers will know what to do to fix it.
