Description Ben Klopfenstein 2016-12-23 06:53:51 UTC

Application: plasmashell (5.8.4)

Qt Version: 5.7.0
Frameworks Version: 5.30.0
Operating System: Linux 4.8.7-040807-generic x86_64
Distribution: KDE neon Developer Edition

-- Information about the crash:
- What I was doing when the application crashed:
Plasma crashed when i was hovering the mouse over thetaskbar entry for Kontact, running via Xorg while Plasma ran in Wayland.
- Unusual behavior I noticed:

The mouse cursor moved smoothly over top X applications, but stuttered and moved with jerky motion when moving over the plasma panel.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

Comment 1 Christoph Feck 2016-12-31 21:23:13 UTC

QOpenGLContext::swapBuffers() calls into libwayland-egl.so causes a crash, not sure if this is valid configuration for using Plasma on Wayland.

Comment 2 Martin Flöser 2017-01-01 09:28:03 UTC

yep, that's valid.

The crash on the X application is probably just coincidence. What we need is a backtrace with debug symbols in the driver. The crash is quite deep down in the driver, so we need to see what it does and then maybe delegate to mesa devs.
