How do you clear the history?
Edit-> Clear & Reset -> scrollbar not updated 
or
Scrollback->Clear Scrollback & Reset (Ctrl+Shift+X) ->scrollbar is updated

No, Scrollback->Clear Scrollback (Ctrl+Alt+H)

With konsole 2.3.3 (kde 4.3.3) compiled from sources I have Scrollback->Clear Scrollback, but no default shortcut Ctrl+Alt+H for this action.
Using this option the scrollbar knob is indeed unchanged.

Konsole 2.4 in recent trunk compiled from sources does not have this option Scrollback->Clear Scrollback anymore, only the options I described in Comment #1, so I do not see a regression.

These 2 were removed from KDE 4.4.

Edit->Clear Display
Scrollback->Clear Scrollback

They were removed as it was deemed they made no sense w/o the 'reset' part.

Huh? That's marginal for 'clear display', and just plain dumb for 'clear scrollback'. The latter (which should have the same effect as '\e[3J', i.e. toss out everything not on the screen) is extremely useful if you've, say, done a build, ran 'clear', ran some other stuff, and now want to throw out the scrollback of the build but need the other stuff still. Or even if you've just run 'clear' and want to clear the scrollback also, but don't want your bash prompt to disappear.

Actually I tend to think going behind the back of the running application and clearing/resetting the screen is questionable.

I hope this will be reverted. (And I'm glad '\e[3J' still works; I am going to be REALLY annoyed if that goes away :-). Which is to say, the code is still there, there is just not a menu item for it any more.)

As for the original bug, I seem to recall this happening in early KDE4, but it has been working correctly for quite some time. Works for me in trunk, anyway (I am using "echo -e '\e[3J'" for step 4.)

Remind me, was there a discussion about this somewhere?

That case is handled by Clear and Reset (Ctrl+Shift+X) - Konsole jiggles the terminal window size to make the shell redraw the prompt (works with bash, not with some other shells).

Only the GUI menus were removed.

Clear Display just cleared the display and left the cursor were it was - which makes no sense

Clear Scrollback cleared scrollback but not display - it was thought most people would want the Reset.

It was displayed some time ago; due to Strings issue, 4.4 was the earliest it was committed.

This works fine in trunk, at least with the "Clear Scrollback" from Context menu.

This was fixed sometime in the past.

I feel that this needs to be reopened as I can't make reset OR clear to update the scrollbar.

OK to reopen?

I have to add that I use Mageia 6 and the latest Konsole version (17.12.2) that I even built from the Cauldron src.rpm.

Not sure that this is the right bugreport to type in, but I have the same problem, that if I type reset or clear the scrollbar doesn't update even though the output looks to be cleared.

I would notice if this didn't work as I use it daily.  What shell are you using?  You're not using something like tmux/screen/etc?
