Windows 10: Constant flashing loading icon (blue circle) next to my mouse.

FIX (for me): i closed NVIDIA Container in my Task Manager, then that little blue loading stopped falshing *Biggrin

 

I thought I'd make a quick account to reply with my solution to this as I'd been suffering the exact same issue on a generic PC tower build.

For me it was actually caused by gmail of all things. If I have a gmail tab open in Chrome I get the blue circle blink next to my mouse pointer about every 5 seconds which is highly irritating. As soon as I close the gmail tab it goes away, so I presume that is probably related to gmail's automated mail check.

This is happening on my other machines as well - 1 is a laptop running W7 and the other is another tower running W8.1. If gmail is open on a tab on any of the 3 different OS's I get the blinky blue circle.

 

I actually registered just to expand upon this, as well. I had the same problem with the blinking working symbol next to my cursor.and was searching through these replies to no avail. Then I saw yours and was like: Oh, that's something I actually hav
that I can check.

I didn't want to close my gmail tab if I could help it, though...so I went to check in the settings for anything I could turn off. Lo and behold, I found something that seems to have stopped the blue circle from popping up even with a gmail tab open.

To fix this particular problem with gmail happening, you simply need to turn off the gmail "Chat" service in Gmail's settings.There's a tab there so it should be really easy to find. Of course, if you actually use this service (which I don't), then this won't solve your problem...but it's what fixed it for me.

Hope that helps someone else, as well~ *Smile
