I've just install windows 10 ltsc 2021 on my laptop (rog flow x13 2021, AMD 5800HS version, all drivers from windows update), an annoying problem occurs: 1. About every 10 sec, a circle appears at the top right corner of the mouse cursor, it rotates for about 1 sec. This happens all the time when windows is running. 2. I checked the taskmanager, no strange process running nor high resource occupation. It's a clean windows with kms activation and a few credible apps (chrome, office, etc.) 3. I noticed when the circle appears, the CPU Speed runs up to 4Ghz, and after that it drop to 3.* Ghz. CPU Usage is always normal. 4. Except that, nothing wrong happens. Anyone know what's wrong? Please help. ps. Does it relate to the AMD ftpm issue?
