[Pkg-xfce-devel] Bug#885970: xfdesktop4: Divide error and crash

[Lorenzo Ancora]

Package: xfdesktop4
Version: 4.12.3-3
Severity: important

Dear Maintainer,
sometimes using GPU intensive or full-screen applications may cause xfdesktop
to crash. The software is stable and this very happens infrequently, but when
it happens the kernel ring buffer contains messages like: "trap divide error
ip:55885b6c09db sp:7ffc8bd04200 error:0".

Kernel ring buffer OUTPUT: https://paste.debian.net/1003084

Restarting xfdesktop works correctly after the crash.
I am using Openbox and a desktop with HD background containing only a few
executable links.
