I’m trying Kicad 5.1.6-1 on win10 but the window data seems to be mirrored, i mean i’m viewing the schematic from behind, which seems to unintuitive at best
That’s a known problem with some virtual system(s) which won’t be fixed because it’s not fault of KiCad. I don’t remember if there’s any workaround. Try switching to Preferences -> Modern Toolset (Fallback).
