i also have the coredump from kwin but i can't attach it because it's too big
Comment 4 Zamundaaa 2024-09-26 16:09:34 UTC
Please get the full backtrace with debug symbols. You can do that with
> coredumpctl debug kwin_wayland
and then
> bt

just informing that i updated to plasma 6.2.1, and the crash only occurs in the SDDM, so i set it to login automatically and it logins just fine, but if i disable the auto-login, or log out from my account it crashes, so wouldn't it be a SDDM bug?
