Thank you for that information.
I was already getting a bit of a feeling like "oh boy, this is not on a simple
patch level anymore". And your explanation confirms that.
I'm sorry, but this is not on a patch level anymore that i feel comfortable
I would have been fine by touching Konsole code and perhaps a few other
framework libraries to get this implemented. But touching XLib/XCB is a
showstopper for me, that's where i drop out.
We're back to one of my earlier assessments for this issue. It's very difficult
to implement while the basic functionality is so easy to get.
Good thing is that every aspect of this issue and how to implement it is now
described in this bug report, hehe.
