Hello, and thanks for the lovely app. It's been a pleasure to discover it!
I have a small phone with a big resolution (Asus Zenfone 8) and despite having a good vision I have to set the font size to largest to have a good experience on the phone overall.
This settings affects the rendering of hiraganas, kanjis, etc. and as a result they overlap the whiteboard and parts of the character becomes unreadable over the darker background. See the attached screenshots below.
I don't know if this is something that would be easily solvable, but it would make a huge difference for high dpi users, and I think we're moving towards higher resolutions anyway so this might be a problem that stays around.
All the best,
jedd
