Hi Moni,
There indeed is an alternative to "clicking madly" :D - the game features an auto-progression mode that lets the text flow automatically. You can adjust the reading speed as well. If you want to replay some sections in order to explore new branches of the story, there is also an auto-skip mode that fast forwards through sections you've already seen. Hope this helps :)
Concerning the resolution bit, I've checked with tech, and they assume it could be a proton thing since the switch version was designed to run in 720p, and that does sound good. They suggested you play around with resolutions to see if sth looks better on your system.
Hope this helps,
Cheers,
Michel
