If you listen to "Leaving Home Ain't Easy" you will notice that it's not comfortable to toetap along it's 4/4 beat. This is because the groupping of stressed notes keep following a 3 + 3 + 2 pattern, that is often referred as bulgarian rhythm which is an example of the compound meter. Sometimes the groupping of arpeggiated notes articulate this beat. Compare the 4/4 beat with 3+3+2 beat in beat map:
1 2 3 4 1
* . * . * . * . * : 4/4 beat
* * * * : 3+3+2 "Bulgarian" rhythm
This 3+3+2 rhythm is usually used just meausure-long in Queen songs, sometimes longer (eg. intro of "Liar" or "Silver Salmon"). There are other frequently used compond patterns. For example two-measure long 3+3+3+3+2+2 pattern which is rarely used continuously as meter, more freqently in single mode. Considering how widespread this pattern in popular music since the ragtime era is ("Summer Of '69", "Something") , it is rarely mentioned and discussed in text books.
A similar, but less frequently used pattern is 2+3+3+3+3+2 (non-Queen examples: "I Got Music" "Satisfaction" "Simply The Best" or "Freestyler").
There are many other less frequently used patterns (Eg. the "Bo Diddly" beat in "Faith").
