Briefly flashing parts of windows from another workspace during overview transition
Affected version
- Fedora 32 (Workstation Edition)
- GNOME Shell & Mutter 3.36.5 (-1.fc32)
- Wayland session
Bug summary
Sometimes, when leaving the overview, you can see a flash of the window(s) from a different workspace.
Steps to reproduce
Good news — there's a reliable way to reproduce it:
- Open some window and make sure it touches the bottom of the screen (easiest if you just maximize it)
- Go to the workspace below, open any window there
- Open the overview
- Grab the window, then release it (don't move it anywhere, just grab and release)
- Leave the overview
Just below the panel, where the search field has been, you should see the flash of the window from that workspace up above.
Relevant logs, screenshots, screencasts etc.
It's reproducible in nested Shell, so here's a Peek recording:
