I've been noticing that Windows 10 occasionally drops rawHID packets. On my development machine (desktop) about 1 in every 100 packets gets dropped. On my Surface Pro (2017) with battery saver turned on, it's about 1 in every 50 packets. I believe this to be a Windows 10 only issue, as it has only recently cropped up in the last year or so, and macOS seems to be unaffected. I'll be doing some extensive testing over the next few weeks and report my findings.
