Bug 450091

SUMMARY

When operating in multi-screen, new windows of for example Dolphin and Konsole are usually placed on the secondary screen instead of the primary screen. When moving the window to the primary screen, adjusting the size and closing the window, the size is not restored when opening a new window.
When adjusting the size before moving the window to the primary screen, the size is restored after closing the window and opening a new window.



STEPS TO REPRODUCE
1. Connect an external screen. In my setup the external screen is primary and to the right of the laptop
2. Open a new instance of for example Dolphin or Konsole. In my case, the window is usually placed on the secondary (left) laptop screen.
3. Move the window to the primary (right) screen, adjust its size and close it
4. Open a new window of the application. The previously adjusted size is not restored
5. Adjust the size, close the window or move it to the secondary screen and then close it
6. Again open a new window of the application. The previously adjusted size is now restored

OBSERVED RESULT

The manually adjusted size is not restored (when the window is moved to the primary (or generally another?) screen before adjusting the size)

EXPECTED RESULT

The window size should always be restored
