I'm attaching the full journal here. I also have the coredump but am reluctant to post it here, because the desktop session might contain sensitive data. I'm on Tumbleweed 20240329 and have no idea what could have triggered this issue or how to reproduce it. -- You are receiving this mail because: You are on the CC list for the bug.
