Bug ID: 494820
Summary: Occasional crashes in
QtWaylandClient::QWaylandShmBackingStore::resize()
when switching sessions
Classification: Applications
Product: kate
Version: Git
Platform: Other
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: sessions
Assignee: kwrite-bugs-n...@kde.org
Reporter: n...@kde.org
Target Milestone: ---
I have two sessions in Kate, and the "Recent Sessions" button in its toolbar.
These sessions often end up with different saved window sizes (which seems like
it could be relevant information, based on what's in the backtrace).
Sometimes, when I click on the "Recent Sessions" button and switch to a
different session, Kate immediately crashes with this backtrace:
#0 __pthread_kill_implementation (threadid=<optimized out>,

44 return INTERNAL_SYSCALL_ERROR_P (ret) ? INTERNAL_SYSCALL_ERRNO
