I uninstalled my v3 and installed v4 and Im having issues... I can connect (KVM) just fine to my secondary PC but there is a huge delay on the primary side. I can see my secondary PC monitor while controlling it with my primary. The actions I make on the primary side are immediate on secondary. But takes 5-10 seconds to catch up on primary. Also, the video degrades on the primary side after being connected for a while. Almost like what you would see if your gfx card was taking a dump.
I am also disappointed to see you didn't make changes to the sidebar. I requested years ago to make the screens in the sidebar bigger so those of us that are not running 800x600 res can see whats going on other pcs in the network. smh
No Linux or Pi support????
