>> Here is (I think) a recipe to demonstrate what the OP has in mind

>>
>> 1. emacs -Q -nw
>>
>> 2a. if your terminal emulator has a light background: M-x load-theme 
>> RET modus-vivendi RET
>>
>> 2b. if your terminal emulator has a dark background: M-x load-theme RET 
>> modus-operandi RET
>>
>> Observe at that point that the last character (the one at the bottom 
>> right) does not have the background color of the chosen theme.  So far 
>> so good.

> The OP filed a bug for this, and he might work on it he said.

Yes, my understanding is that this bug (bug#57728) is a dependency for 
bug#57607.
