Bug ID: 361643
Summary: kwin_x11 crashes via chrome-remote-desktop
Product: kwin
Version: 5.4.2
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Application: kwin_x11 (5.4.2)
Qt Version: 5.4.2
Operating System: Linux 4.2.0-35-generic x86_64
Distribution: Ubuntu 15.10
-- Information about the crash:
- What I was doing when the application crashed:
running kde in Xvfb launched by chrome-remote-desktop, Power Management
disabled, connection is successful but a dialog is presented "Kwin is
unstable.... you can choose another window manager", however only kwin_x11 is
offered in the dropdown.
Kde runs correctly in a hardware display, but not in a frame buffer.
The crash can be reproduced every time.
-- Backtrace:
Application: KWin (kwin_x11), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
