Lol idk if you still would play this but I had the exact same problem and managed to kind of fix it. I went to my settings and decreased my display resolution from 1920 x 1080 to 1680 x 1050. In other words, decrease your resolution causing the quality to probaby decrease, but it also shrinks your screen so to fit most of the game into view. My selection dot was still a little to the bottom right but I was able to read the conversation and finish the game properly. Hope you get to try the game and enjoy.
