The flashing loading icon next to the cursor seems to be a common occurrence for those using Windows 10. If you're experiencing the same issue, updating the ATK package may solve the problem on your ASUS device. You can download it from the ASUS Support website. Just enter and select your product, click on 'Driver & Tools', select your OS and find the ATK package.
If you're running Windows 10 (64 bit), you can download the ATK package directly from here.ATKPackage (For Windows 10 Upgrade)
ATKPackage includes ATKACPI driver and hotkey-related utilities.
To avoid displaying OSD abnormally due to compatibility issue after upgrade to Windows 10, please update ATKPackage to v1.0.0038 or above.
Similar issue is apparent on HP machines to which a solution lies in disabling the SimplePass software according to this thread. (Doing so would render the bio-metric hardware useless and I find it hard to imagine that this hiccup hasn't been solved by now. I would suggest having a look at the HP support site for driver updates.)
