Bug ID: 414555
Summary: KWin/libQt5Gui.so.5.13.2 crashes when locking screen,
listening to music, running virtualbox, etc
Product: kwin
Version: 5.16.5
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: initial.d...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.16.5)
(Compiled from sources)
Qt Version: 5.13.2
Frameworks Version: 5.64.0
Operating System: Linux 4.14.138 x86_64
Distribution: "Gentoo Base System release 2.6"
-- Information about the crash:
- What I was doing when the application crashed:
I had a virtualbox virtual machine running, I was listening to music using
Strawberry music player off a secondary internal laptop drive and running other
applications such as email, terminal, browser, slack and one or two others.
This is the second time this has happened. I haven't repeated the exact steps,
but I may try that soon in the future. This all started to occur once I
upgraded my qt versions and some plasma apps. I use gentoo, qt 5.13.2 packages,
kscreen and kscreenlocker 5.16.5.
I've locked this machine a couple times previously today without issue, but
also without listening to music. Virtualbox was running then. Started machine
up from cold boot this morning.
- Unusual behavior I noticed:
Lock screen appears in the form of the lock screen background, but no password
prompt. It holds at the background for a few seconds, then flashes to black,
then to background, then to black again. journalctl reports a segfault.
I'm concerned that perhaps this bug relates to the media player widget on the
lock screen and strawberry, which I compile from git source master branch. I
have also updated Strawberry close to when I upgraded qt5 libs. To add, nvidia
drivers were also updated recently (390.x series for a 2000M quadro card via
emerge).
Once lock screen crashes, I lose my background and plasma widgets/panels, black
screen background
The only way I have been resolving this is to reboot.
