XWayland windows are duplicated on external monitors if they are maximized on main monitor
Affected version
- OS: Ubuntu 22.10
- GNOME Shell version: 43
- The problem occurs in Wayland sessions (X11 not tested here)
Bug summary
When I maximize any XWayland window on my internal (main) monitor, it is replicated on the external monitors too. No issue with native Wayland windows (GTK3 / GTK4 apps)
Steps to reproduce
- Maximize the window of an X11 (GTK2) app on the middle screen
What happened
The window is displayed on all monitors (see videos above).
What did you expect to happen
The window must be displayed only on one monitor.
Relevant logs, screenshots, screencasts etc.
Here is a video of the bug I took with my smartphone:
I also tried to use the screen recording tool from GNOME Shell, but strangely it does not display the problem:
