just another screenshot on d780. the bottom-right of the portrait-left display (my right.display but was default-left on boot) or the area that is BELOW the other screen is where it's flashing (stopped awhile back now; when I clicked the SHOW.DESKTOP type button in error thinking it was a menu)
/var/crash/ is also empty on this box and again I see nothing useful in dmesg or journalctl ** Attachment added: "Screenshot at 2021-09-23 03-53-48.png" https://bugs.launchpad.net/ubuntu/+source/mate-control-center/+bug/1944661/+attachment/5527244/+files/Screenshot%20at%202021-09-23%2003-53-48.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1944661 Title: changing screen positions (mate-control-center.displays) caused one display to become unreadable/unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mate-control-center/+bug/1944661/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
