On my PC when the OneDrive "Files On-Demand" option is activated, thumbnails for PDF files stop working in Windows Explorer (Windows 10 64 bits). For me, this does not affect JPG pictures however. Note that the PDF thumbnails continue working in folders that are not synchronized with OneDrive. Eventually, the problem is "solved" when unchecking back the OneDrive "Files On-Demand" option.
We’re actively working on some architecture improvements that will significantly help reduce cases of high CPU.
