 I think these days no hacks or tricks are needed anymore (indeed, that means 
only 'really needed' - there are enough broken apps that just don't happen to 
cooperate nicely without hacks and tricks). XFixes can give notifications 
about clipboard changes. There are proposals for notifying about apps owning 
the clipboard quiting, for limiting the size of the transfers, there are 

 Which again makes me wonder what exactly you'd like to fix and how. I 
personally find your list of problems and your proposal too vague.

 This must be a misunderstanding. I doubt Aaron Seigo has even touched 
internals of Klipper, let alone being its author. The original author of 
Klipper is Andrew Stanley-Jones, Carsten Pfeiffer used to be the maintainer 
until recently, and Esben Mose Hansen is the current maintainer 
( - 
search for 'createAboutData'). I'm actually not sure how much these people 
know about the underlying X details, because they're shielded by the 
high-level QClipboard API. The person fixing the underlying X details usually 
happens to be me.
