I think this is a consequence of your desktop being 18432 pixels wide. Each 4K monitor is 6144 logical pixels wide because of a custom Xrandr scaling factor of 1.6.
Turning off screens wouldn't fix it, only unplugging them might. But still this sounds like a GTK bug because modern Nvidia GPUs like yours should be fine with an 18K desktop. ** Bug watch added: gitlab.gnome.org/GNOME/gtk/-/issues #3050 https://gitlab.gnome.org/GNOME/gtk/-/issues/3050 ** Also affects: gtk via https://gitlab.gnome.org/GNOME/gtk/-/issues/3050 Importance: Unknown Status: Unknown ** Changed in: gtk+3.0 (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/2004533 Title: Gtk-WARNING ... drawing failure for widget ... invalid value (typically too big) To manage notifications about this bug go to: https://bugs.launchpad.net/gtk/+bug/2004533/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
