Bug ID: 377321
Summary: KWIN crashes sometimes when opening VBOX client
Product: kwin
Version: 5.8.4
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: ebelc...@eacbelcher.net
Target Milestone: ---
Application: kwin_x11 (5.8.3)
Qt Version: 5.6.1
Frameworks Version: 5.26.0
Operating System: Linux 4.4.49-16-default x86_64
Distribution: "openSUSE Leap 42.2"
-- Information about the crash:
- What I was doing when the application crashed:
On starting a VirtualBox client (Windows 10) with two screens, one window will
sometimes fail during startup. Disabling and restarting the second screen
resolves the symptom.
VirtualBox Graphical User Interface
Version 5.1.14 r112924 (Qt5.6.1)
NAME="openSUSE Leap"
VERSION="42.2"
ID=opensuse
ID_LIKE="suse"
VERSION_ID="42.2"
PRETTY_NAME="openSUSE Leap 42.2"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:opensuse:leap:42.2"
BUG_REPORT_URL="https://bugs.opensuse.org";
HOME_URL="https://www.opensuse.org/
The problem is a reasonably new one, 4-6 weeks and I believe due to a OpenSUSE
patch. VBOX has remained at the above version since it was released.
The crash can be reproduced sometimes.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
