Apparently it's a bug in libx11, which persisted for a long time but became much more likely with an update in libxcb.

[Bug 1808710] Re: !xcb_xlib_threads_sequence_lost error with GTK2 applications
Unfortunately, setting LIBGL_DRI3_DISABLE to true did not help to bypass the bug. On the other hand, the bug does not manifest itself if there is only one active CPU core. The number of active CPU cores can be controlled by 'maxcpus' kernel parameter: add 'maxcpus=1' to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub, then run update-grub as root. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gtk+2.0 in Ubuntu. https://bugs.launchpad.net/bugs/1808710 Title: !xcb_xlib_threads_sequence_lost error with GTK2 applications To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gtk+2.0/+bug/1808710/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
