Bug ID: 375109
Summary: System settings started glitching and crashed after
navigating quickly in tree mode
Product: systemsettings
Version: 5.5.5
Platform: Compiled Sources
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: kd...@mail.com
Target Milestone: ---
Application: systemsettings5 (5.5.5)
(Compiled from sources)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-59-generic x86_64
Distribution: Ultimate Edition 5.1 LTS
-- Information about the crash:
- What I was doing when the application crashed:
Navigating and browsing through system settings with the view in tree mode.
Limited applications running. Changing between sub-categories inside the "Audio
Output Mode". I switched quickly between the analog stereo and anolog duplex
mode about 5 or 6 times. PC first started to lag and hang before becoming
glitchy and freezing for an extended period of time (2-3 minutes). Once freeze
released, I shut-down settings and was greeted by the bug reporter. Shortly
before initial lagging I noticed that the title text was lingering and
overlapping from one option screen to the next.
-- Backtrace:
Application: System Settings (systemsettings5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
