First step
Activate smart background (based on page) in the settings
Second step
Read a manga
Expected behavior
The background should change color based on the actual manga page
Actual behavior
The background changes correctly when the page is colored, but stays black whether the page is black or white
Other details
Setting the background to smart (based on page and theme) and then returning to smart (based on page) fixes the problem, but only for the actual page and the next one.
