            Bug ID: 348159
           Summary: Kate unresponsive when typing in text (swp file saved
                    after every character, locks up for ~1second)
           Product: kate
           Version: 5.0.0
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: kwrite-bugs-null@kde.org
          Reporter: reinhold@kainhofer.com

Entering Text in Kate (or kwrite) in KDE5  -- as opposed to KDE4 -- is very
sluggish and unresponsive. The typed text sometimes takes a second to appear.

Running kate through strace shows that whenever kate tries to save the
.kate-swp file, it is basically locked up for ~1 second. Since apparently kate
saves the swap file nearly after every character, this means that kate is
constantly locking up for a few moments before the next typed text appears.

Unfortunately, the entered characters are not even in the correct order. In
particular, if I enter:
    if ($ctrsettings["${type}_global"] == 'yes')
then kate actually inserts
    if ($ctrs"ettings[${type}_g"lobal] == ''yes)

In particular, it appears as if all quotes are inserted immediately, while all
letters are inserted afterwards, even if they are typed before the quotes.

Reproducible: Always

Steps to Reproduce:
1. Enter some text in kate
2. The first few characters will appear immediately, but the next will appear
only after a second
