-- Information about the crash:
I was running an apitrace which was spamming multiple lines per draw call in a
Konsole instance that has the history limit set to infinite.
Trying to scroll up while its still printing new lines makes it crash.
The reporter is unsure if this crash is reproducible.
-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
warning: Can't open file /memfd:kwin-dmabuf-feedback-table (deleted) during
file-backed mapping note processing
