For me it compiled very recently.

But one thing i would like to mention. I doubt x.org will ever fix that. we 
have seen it with the tooltip hole bug that was never fixed, and now we needed 
to implement a workaround.
Sure, we can just blame x.org for that the next 5 years, but i doubt that will 
benefit the users in the end.

noenter worked quite well for me on my dualscreen setup (with different 
resolutions). Sure, it needs some improvements, but the basics are working.
I might be naif, but for me such a feature doesn't sound that hard to code, in 
the end its just collision detection code with some special cases.
And i don't think a separate programm should be needed for it to work, but 
that probably kwin should handel it.

anyway, would be nice to see a solution :)

have a nice day
