I haven't experienced the scrollbar aspect (or maybe I just haven't done what you do) but my arrows are missing too.  I'm thinking this is a KDE Blasted Ugly Gotcha (BUG).  BTW, if you haven't already discovered it, if you position your cursor where the arrows used to be the "arrow functionality" still exists (if you can get the cursor position just right).  KDE now has invisible features...

In the past as programmers we were taught more wisdom than today's 
"coders" have been: One of the rules of thumb was:

Don't make any changes in [debugged] program unless they are absolutely 

On a similar note: who remembers netscape navigator (web browser)? It 
was pleasantly not changing its appearance and UI (User Interface) for 
ages. These days Firefox and thunderbird are being rushed with new 
releases. "Releases" full of security holes (take a look at CentOS 
update history: firefox security updates are the most often ones). As if 
they are aiming to beat everybody in version number (currently major 
version in 50th-60th). But they can not beat Microsoft who has a 
release: Windows 2000.
