Bug ID: 363402
Summary: Switching activities regularly crashes plasmashell in
high memory loads
Product: plasmashell
Version: 5.5.5
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: cmdrkot...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.5)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-22-lowlatency x86_64
Distribution: Ubuntu 16.04 LTS
-- Information about the crash:
- What I was doing when the application crashed:
I have 100Mb of 16Gb free and about a gig in swap (was stitching google maps in
krita on a 24000x15000 canvas). Chromium spans two monitors on the second
activity, and krita is on the first. I was grabbing screenshots and dumping
them into krita. Plasmashell crashes every three to four activity switches or
so. Under regular memory conditions, this does not happen.
fwiw, I switch using the switch activity shortcut (meta+tab).
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
