I have been experiences this. Went on a long trip and this is what I noticed. Waze starts with a large turn direction box on the left with a nice readable font on two lines. When a hazard warning comes up (police, pothole, etc), the direction box gets small (one line) with a font thats hard to read and the hazard shows up right below it. When the hazard box goes away, the turn direction box stays small. At least it does for me. I would assume it is supposed to go back to the larger size when the hazard box disappears. It makes navigation difficult when its small as you have to spend more time trying to read the directions.
