experiencing this today with Ubuntu MATE jammy daily - hp 8200 elite sff (i5-2400, 8gb, nvidia quadro 600) (note the real effect of the screenshot is far worse in real life; on movement of the mouse the image on the bottom display changes & it's mostly white-flashes; esp. the trails left by the terminal I dragged a little down onto the lower screen.. see next bug comment for picture after it was moved to lower screen) ** Attachment added: "Screenshot at 2021-12-21 02-53-22.png" https://bugs.launchpad.net/ubuntu/+source/mate-control-center/+bug/1944661/+attachment/5548831/+files/Screenshot%20at%202021-12-21%2002-53-22.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

another picture... if the terminal window visible on the 'lower' screen is maximized; the wrong-background gets covered & flashing effect is gone.. if the terminal is dragged around, it leaves trails (which is why some can be seen as it was opened on the top screen & dragged to the bottom for picture shot). ** Attachment added: "Screenshot at 2021-12-21 02-53-37.png" https://bugs.launchpad.net/ubuntu/+source/mate-control-center/+bug/1944661/+attachment/5548832/+files/Screenshot%20at%202021-12-21%2002-53-37.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

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

[Bug 1944661] Re: changing screen positions (mate-control-center.displays) caused one display to become unreadable/unusable
On this machine - the flashing appears to be only at the bottom of my.right (the portrait-left tilted display).. ie. the section that is below the other display. effect is it's less annoying than the prior box (which was the whole background strobe-like flashing). I've now adjusted the display a few times; all flashing has now ALL GONE but it wasn't the multiple changes that caused it to stop, but my clicking on the SHOW.DESKTOP (which hid all windows) that caused it to stop. dell d780 box - very different GPU to hp (see prior comment) ** Attachment added: "Screenshot at 2021-09-23 03-51-50.png" https://bugs.launchpad.net/ubuntu/+source/mate-control-center/+bug/1944661/+attachment/5527243/+files/Screenshot%20at%202021-09-23%2003-51-50.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

Another QA-test on different hardware - dell [optiplex] 780 (c2q-q9400, 8gb, amd/ati cedar radeon hd 5000/6000/7350/8350) the moment I adjusted screens... same behavior as hp.8200; TRAILS appear in the Monitor.Preferences window, and flashing.background on one display. this box has very different GPU so I didn't expect the issue here - but this looks the same (not as annoying on these displays). screen change this box is swap left-right and my-right display is portrait-right-tilt.

[Bug 1944661] Re: changing screen positions (mate-control-center.displays) caused one display to become unreadable/unusable
Nothing really new in this picture to the last. it's identical to prior uploaded.photo except I adjusted the bottom monitor to be slightly-left (askew) of the top display (thus the black borders shown in the picture). EXCEPT for the TRAILS in the Monitor.Preferences window no issue here at all. Clicking apply & no flashing, system remained usable/readable & perfectly matches what the change I made.

[Bug 1944661] Re: changing screen positions (mate-control-center.displays) caused one display to become unreadable/unusable
at this time I've re-opened the Control.Centre.Displays option (top display), and altered the relative position of each other.. Please NOTICE the SHADOW/TRAILS of the movement I made of the 'green' or originally 'right' monitor which was dragged to be below the left one. Also NOTICE all trails on the lower-display are now gone; so has all FLASHING/STROBING on that display (it's now static). It's now 100% usable & readable. The trails being left on PS: I wonder if this issue is nouveau related, and NOT a Ubuntu-MATE issue; but again whilst I'm convinced I've had this issue before, I didn't find bug reports about it. From this point on the system experience was GREAT (making it both easier for me to type in the problem, but now I need to describe a condition I saw in the past - no longer occurring) ** Attachment added: "Screenshot at 2021-09-23 02-50-05.png" https://bugs.launchpad.net/ubuntu/+source/mate-control-center/+bug/1944661/+attachment/5527169/+files/Screenshot%20at%202021-09-23%2002-50-05.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
[Bug 1944661] Re: changing screen positions (mate-control-center.displays) caused one display to become unreadable/unusable
another pic.. the top screens with terminal is perfectly calm & useable. bottom screen (where window trails exist) is flashing/strobe-like It's mostly the background that strobes; the windows themselves are somewhat usable/readable - caja is shown here and were it not for the flashing of wallpaper & background-stuff, it's likely 100% usable. ** Attachment added: "Screenshot at 2021-09-23 02-42-30.png" https://bugs.launchpad.net/ubuntu/+source/mate-control-center/+bug/1944661/+attachment/5527167/+files/Screenshot%20at%202021-09-23%2002-42-30.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
[Bug 1944661] Re: changing screen positions (mate-control-center.displays) caused one display to become unreadable/unusable
You'll note the lower display has a mess of windows.. What the picture does not show is that the whole screen is flashing/strobe like; it appears a messy-clear image on the picture; but the image is not actually static but flashing... I've since further tested & adjusted display position again (when the flashing stopped) so I can't describe what it was like that well; but it was very irritating & made it difficult to concentrate even on the one display that was perfectly normal FYI: I'm still convinced I've experienced this before; but I can't find bug reports on it, and these actual screens are shared with other boxes; so I maybe thinking of the hp dc7700 (another box that uses same screens/keyboard/mouse etc) ** Attachment added: "Screenshot at 2021-09-23 02-38-02.png" https://bugs.launchpad.net/ubuntu/+source/mate-control-center/+bug/1944661/+attachment/5527166/+files/Screenshot%20at%202021-09-23%2002-38-02.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
