Hello everyone.
I’m using Kubuntu, Netrunner not 
, but since Bluesystems is sponsor of KDE, I take the liberty of commenting here a problem that I (and you) have and that I suppose your may be interested.
I have reporting a bug on launchpad and KDE which I consider very annoying and interests bad for KDE (causes a bad impression).
https://bugs.launchpad.net/ubuntu/+source/kde-workspace/+bug/1167455
https://bugs.kde.org/show_bug.cgi?id=318151
It seems that ignoring me. :-/ managers of Netrunner may have more luck.
Steps to Reproduce: (e.g. Netrunner in English with English (US, international with dead keys) keyboard layout)
1- Open Kate editor
2- write something to check that dead keys work
3- Press alt+F (to open File menu)
4- Press right arrow key (to open Edit menu)
5- Press esc (to closse menu)
6- write something to check that dead keys work

In the case of not fix the bug, I’d be willing to use any distro that effectively implement mitigation measure. More in Spanish:
