Today I got the coredump, but ubuntu-bug cannot upload it, saying "ValueError ('not enough values to unpack (expected 2, got 1)',)". So I use "ubuntu-bug xwayland" command, and attached the generated report. This crash now seems only happens when the system is under load for some time (in my case high cpu usage).
gdb stacktrace of this coredump, if anything helpful: Reading symbols from Xwayland...Reading symbols from /usr/lib/debug/.build-id/65/efba1189e8c1122d2e74c13bf7e54825c3e367.debug...done. done.
