Loading custom background image from a path containing uppercase letters will crash
Hello,
I tried to load a background image generate during a previous run and I'm getting "CRITICAL Could not read the image file"
I ran a test and it seems that the only reason this problem occurs is because there are capital letters in the path.
With background image in /tmp/test/background.png: Working
