I can confirm this issue is NOT Lubuntu specific.. I just experienced this exact issue on Fedora 33 LXQt 0.15.0, Qt 5.15.2
I have NOT experienced this though in opensuse which is a later LXQt (this is more noticable due to https://bugs.launchpad.net/ubuntu/+source /lxqt-config/+bug/1905947 which causes the monitor configuration to be set on each login, which impacts Fedora 33 just like Lubuntu, but not the later opensuse LXQt 0.16) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1845756 Title: lubuntu 19.10 strange movement of wallpaper on monitor.settings change To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxqt-session/+bug/1845756/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
