I’ve noticed two weird things on my new system.
I transferred my old 2TB SSD with my OneDrive files on and started to sync the files, and everything went smooth except ~4000 files were stuck updating (out of more than 100k). For some reason, I did not have read privileges for these files which were randomly distributed in different folders, even though I’m running an admin account. I could copy the files out of OneDrive, it would prompt me for admin rights and then I could read the files. So I had to remove and then enable read rights for admin in my OneDrive folder, and that fixed it.
The other problem I’ve encountered is that sometimes I exit a game, my windows can only maximize to the top quarter of the screen, and I can’t drag them larger. I can move the curser everywhere, but all windows and programs maximize to the top quarter of the screen until I reboot the system.
