Weird Display Issue?

Has anyone else had this issue with random circles appearing in their volumes? The issue only appeared when I switched to the more recent version of 3D Slicer. The size/configuration of circles does not change when I zoom in/out. Any input on how to fix it would be greatly appreciated.

Operating system: Windows 10 Pro
Slicer version: 4.12.0-2021-09-17
Expected behavior:
Actual behavior:

Those are the control points of the annotation ROI widget corrupting the alpha channel of the volume renderer.

You can probably make those go away by enabling/disabling depth peeling and/or using the new markups ROI widget, or just by hiding the annotation ROI widget.
