Overview renders window twice
Affected version
- OS: Fedora 31
- GNOME Shell using Wayland: 3.34.4
- NVIDIA driver 440.64
Bug summary
When in overview mode, gnome-shell sometimes renders the contents of one window twice. In the attached screenshot, Firefox, VS Code and Thunderbird are open, but the Thunderbird window is rendered as VS Code in the overview. It doesn't always happen, but it appears to be more frequent when an application based on Electron (such as VS Code or Slack) is open.
Steps to reproduce
- Open multiple applications, one of which is based on the Electron framework
- Enable overview mode
What happened
Some windows in the overview are replaced with the contents of another window.
What did you expect to happen
The overview should display the actual content of each window.
