This bug is easy to duplicate. Here are the steps: 1. Install Ubuntu 19.10 with a fresh install. 2. Install all the updates. 3. Install the gnome-tweaks tool. 4. Open the gnome-tweaks too. It may not occur immediately, however, once you get down to the "Window Titlebars" section, change the Titlebar buttons or Placement options and at the point the tool will never work again and will be liked originally described.
The up-and-down arrows will allow you to change sections. You just have to make sure you move your left arrow first to ensure you are all the way on the left side before moving up/down. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1846445 Title: 19.10 gnome tweaks flashing and unusable To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/zulucrypt/+bug/1846445/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
