I have the same issue. It forced me to revert back to 19.04 from latest ver. of 19.10.
It was already a problem since week prior to release of 19.10 (when I first tried). 19.10 latest ver on Intel Graphics 530. This bug is impacting on: modesetting driver xorg as well as intel driver xorg. I also tried Wayland to same result. This is impacting a fullscreen video game I'm playing in OpenGL. ** Also affects: gnome-shell (Ubuntu) Importance: Undecided Status: New ** No longer affects: gnome-shell (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849787 Title: The dock is shown in front of full screen windows since 19.10 To manage notifications about this bug go to: https://bugs.launchpad.net/dash-to-dock/+bug/1849787/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
