It has been fixed, all white background now.
Sorry to bother you again! I have astigmatism and it's still hard to read after the fix T.T
I don't know if it's a device issue but the text is in a very faint grey color on white background so it's hard to read. Could I suggest a mode with black background and white font just like here ?
Edit: Thank you for changing it, it's perfect now :)
