I see this also using the Edge browser on Windows 10. It happens constantly. It only happens with Google maps (both map and satellite view), never with Leaflet. Whole sections of icons disappear after zooming in or out or after grabbing and dragging the map, then reappear after another zoom in or out or grab and drag. This happens whether zooming with my mouse wheel or with the onscreen + and - buttons. The area affected can be different sizes, but how large or small the area is is difficult to determine since, of course, caches are randomly distributed.
Note that this does not happen every time I zoom in or out, or every time I grab and drag the map, but it does happen frequently.
It's quite frustrating because I am never sure if I'm really seeing all the caches. I have to keep zooming in and out until I'm confident all are being displayed. I look forward to this being fixed.
