Since somewhat recently, the password field of the ksshaskpass dialog no longer is focused per default. I now have to press Tab once before I can type my password, which is rather annoying. I am not entirely sure how this started happening; there was no ksshaskpass update. Still, I would not know where else to report this either. I am using Debian testing and upgraded the KDE packages to unstable, which means I have (most of) KDE 5.10.5. In particular, Kwin and Plasma are on that version.
