Thing is, I used the old OSS Synergy some 15-20 years ago, across Linux, Windows and I believe OSX as well (although I am not 100% certain about the latter). It worked absolutely flawlessly for several years while I used it and I loved it dearly. Fast forward (I had no need for a software kvm until last year) and I use Barrier now and it barely works. Autostart on Windows doesn't work at all, the installer failed to create certificates so nothing worked until I created them manually and sometimes the keyboard dies completely or exhibits frustrating bugs which only a reboot can solve. It's baffling how this used to work so well and is barely usable 15+ years later.
