I'm currently wanting to use an old piece of Python code called python slideshow with time and weather (github). I'm using a Raspberry Pi and I've got it all setup and it works perfectly in landscape (normal) mode. This is a slideshow application which has a weather and time overlay developed on Pygame.
I want to use the application in portrait, however when I rotate my screen in the /boot/config.txt using display_rotate=1 (or 3) and restart the slideshow, everything appears to work, the weather overlay appears in the bottom left/right as it should, however as soon as any part of the weather or clock or day update, it prints the text over itself.
Has anyone got an idea of what might be causing this behaviour? I can't see anything in the code. Here's the python file from Git below and I have attached a screenshot of the strange behavour[image showing text overlay issue in the clock in this instance][1]: Python slideshow with time and weather on github
