This is happening to me too. Fresh install of Debian 11, primary DP landscape, secondary HDMI portrait. Two effects:
1. A window on the right of the primary screen moves to the left of the primary screen. Another window on the left of the primary screen does not move. The moving window also resizes, although this contains Terminal and may be resizing to default row/column settings. 2. A maximised window on the secondary screen is moved down so there is a one-line gap at the top, despite still being maximised. Un-max/max removes the gap. It seems to happen when screen is blanked. I have disabled screen locking so don't know if it happens when screen locked too. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1927948 Title: Windows switch monitor after resuming from sleep To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-shell/+bug/1927948/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
