            Bug ID: 426658
           Summary: Okular crashed while annotating document
           Product: okular
           Version: 1.11.1
          Platform: openSUSE RPMs
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: hiwatari.seiji at gmail.com
  Target Milestone: ---

Application: okular (1.11.1)

Qt Version: 5.15.0
Frameworks Version: 5.73.0
Operating System: Linux 5.8.7-1-default x86_64
Windowing system: X11
Distribution: "openSUSE Tumbleweed"

-- Information about the crash:
- What I was doing when the application crashed:
I was annotating a document when Okular suddenly crashed.
I am mostly using the highlighter tool to mark parts in the text. Directly
after having used the mouse to select a part in the text, I double click on it
to open the comment window for this new highlight.
Though since the new version, this got so slow (up to 1 second for the
highlight to appear after releasing the mouse), that I often add a second
highlight below where I double clicked, before the first highlight is even
shown.
Like this, I have multiple times ended up in a state where the highlighter tool
is still active, but I am unable to click-drag an actual highlight. Just
nothing happens.
I was in this state when it crashed, so that might be related (and sounds like
a race-condition to me).
I am basically saving the document (ctrl + s) after each annotation - if that
changes anything.

-- Backtrace:
Application: Okular (okular), signal: Segmentation fault
