I also encountered the same issue. The affected software from the official software sources includes GParted and Software & Updates (Software Updater). Third-party software includes Zotero, Electron-based software such as Typora, etc.
I also noticed another issue that might be related to this: When there are other normal windows in the workspace, clicking on certain areas of the affected software causes it to minimize or invisible. Steps to reproduce these issues: 1. Open Chrome and make it full screen 2. Open Software & Updates, there is no shadow on the window edges 2. And click near the edge(for example, click on the blank area to the left of the 'Close' button. ), and the Software & Updates window becomes invisible or under the chrome window. autologin is enabled and Xorg is used -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/2064177 Title: Window borders and shadows missing from GTK3 dialogs (if autologin is enabled and Xorg is used) To manage notifications about this bug go to: https://bugs.launchpad.net/gtk/+bug/2064177/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
