Looking Glass is lossless, so provided you can do your color calibration under Linux then it would work fine.
1) It's not a signed executable (FOSS project, signing is a PITA without corporate sponsorship)
2) Microsoft Defender flagged the exe for wanting admin privs
3) Google were dumb and flagged us because MS did
4) All other AV vendors flagged us because google flagged our website.
We had to put the exe into a password protected zip to stop Google flagging us as we couldn't convince the idiots (robots) there that it was a FOSS project with all sources available for review. 1. We are working on it
2. Not if it's a vGPU or a Quadro where EDID spoofing is allowed
3. No, we capture everything now, even the windows Login screen and windows updates, etc.
4. Yes
5. Very yes!
