Bug ID: 451425
Summary: KWin crashed after opening the Application Menu (menu
style) from the panel
Product: kwin
Version: unspecified
Platform: Neon Packages
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: david.hu...@mailbox.org
Target Milestone: ---
Application: kwin_x11 (5.24.80)
Qt Version: 5.15.3
Frameworks Version: 5.92.0
Operating System: Linux 5.13.0-35-generic x86_64
Windowing System: X11
Distribution: KDE neon Unstable Edition
DrKonqi: 5.24.80 [CoredumpBackend]
-- Information about the crash:
- What I was doing when the application crashed:
I just connected to the computer with x2x, while it was showing the empty
desktop immediately after starting up. I hovered the Application Menu launcher
with the physical mouse, then used the x2x mouse to click it. I moved the x2x
mouse to select an application, and KWin instantly crashed, automatically
restarted, and crashed again. The third KWin survived.
I can imagine that the instant cursor jump, which occurs when switching from
the physical mouse to the x2x mouse, caused this crash. For example, the x2x
cursor may have hovered some part of the menu before it was sufficiently
initialized. When using only one mouse, there would be sufficient delay between
clicking the launcher and moving the cursor over the menu.
- Custom settings of the application:
The panel is moved to the top screen edge. Besides that and x2x, I don’t know
of potentially relevant configuration.
The reporter is unsure if this crash is reproducible.
-- Backtrace:
