I know it's clear this isn't an issue for the masses, but this is still incredibly frustrating to see no movement here. Not using "High Performance" mode means we're using Screen Sharing of pre 2007, it's not ideal and isn't a permanent fix. It'd be great to get this on some sort of roadmap for investigation and fix, I've been dealing with this for months now and it's super annoying to finally get too frustrated to search out for support, find this thread and see nothing but acknowledgement. I should also chime in, this bug only happens on version 8, which makes me regret updating this headless machine to the Electron app :(
