It was indeed on older official releases on those older machines, I never got into the nightly builds that much. I will try both the latest release and latest build this weekend when I work on the new hardware, and I'll report any showstopping bugs. Now that I think about it, it definitely could be USB related on those other machines too. I've used the same cheap USB KVM for years and it has polling issues in Windows 10, I didn't even consider that might be the source of my issues elsewhere. I'll try it without the KVM and see what happens. Thanks!
