Bug ID: 416472
Summary: KWIN crashed when resuming from sleep; Sending back to
sleep and awakening again it started but displays odd
behavior.
Product: kwin
Version: 5.17.5
Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: michaelsbarr...@gmail.com
Target Milestone: ---
Application: kwin_x11 (5.17.5)
Qt Version: 5.13.2
Frameworks Version: 5.66.0
Operating System: Linux 5.3.0-26-generic x86_64
Distribution: KDE neon User Edition 5.17
-- Information about the crash:
- What I was doing when the application crashed: Waking from sleep mode.
- Unusual behavior I noticed: Initially I had one monitor showing only black,
second monitor was mostly black, with a couple of display artifacts showing
parts of two application windows. I put the machine back to slep by pressing
the power button and re-awakened it, also using the power button. Now the
display is mostly there, the application launcher displays only a blank window,
and any windows that were already open will only take up half of the vertical
monitor space when maximized. I have not yet rebooted, will do so next. Using
KDE Neon with the NVIDIA 430.64 drivers from the repository.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
