sudden crash of X server with malloc in the journalctl

Wed Apr 10 09:21:40 UTC 2024

Hi Olivier,

yes, that sounds familiar, but the package versions do not match mine. I am
too much of a user to find the link between the given links and possible
versions on my machine. Also which package to downgrade to fix this until
the merged fix is rolled out.
The package I could find closest to the name is
xserver-xorg-core/jammy-updates,jammy-security,now
2:21.1.4-2ubuntu1.7~22.04.10 amd64
which does not resemble the versions mentioned in the link.
Any ideas? (Or will the fix be rolled out very soon?)

Jan (that gets used again to save every 30s when not working in IntelliJ)
