Hi, any news on this? I have the same issue on Ubuntu 18.04.3 LTS. I have upgraded from 16.04 recently and started to have this error. This bug also affects leafpad and probably meld. meld has a fix or workaround but can't remenber what was the fix, i had to install the latest meld from source, that fixed the problem.
I would like to hear if someone found any workaround or is it a bug on libX11? https://github.com/mirror/libX11/blob/master/src/xcb_io.c#L259 Looks like google chrome freezes from time to time in a very similar way but could be a tone of things, just for the record. What can i do to help? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782984 Title: PCManFM freezes with Assertion `!xcb_xlib_threads_sequence_lost' failed when clicking on a file or folder in 18.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pcmanfm/+bug/1782984/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
