Maybe its the games I have played but my last pc was connected to my tv exclusively for 5 years and never saw that UI issue. I definitely had issues that sometimes needed addressing, but that wasnt one. I thought it worked good enough, but yeah the keyboard and mouse was always annoying. I used the Logitech all in one which was pretty small and mouse pad on the right side from the couch. For the most part I used it more for video playback though so I was in Kodi a lot and I would then use my phone as the remote control.
