If you haven't solved the problem, I found an answer by JohanElzenga, Community Expert that solved the problem of seeing the bounding circle and center on the radial gradient tool:
"...click on the three dots behind Show Overlay. Then check the 'Show pins and tools' option." See the attached screenshot from his post. Also here is the link to view the entire post. Hope this helps:

@paulv43756212 more than likely it's a GPU related issue, to test I disabled the GPU in preferences and restarted Photoshop and didn't get the circle, enabling the GPU again and it works fine.
So what GPU do you have in your system and are the drivers up to date, it may help if you could post your Photoshop system info, in Photoshop go to Help > System Info, hit the copy button and paste the entire thing into this thread
