Window shifts slightly each time it is hidden and shown in fullscreen mode on Linux

[hidayet-poscu]

In my Linux application, when running in fullscreen mode, every time I hide and then show the window again, it shifts slightly outside the screen. Over time, repeated hiding and showing causes the window to move further.

Steps to Reproduce

1. Run the application in fullscreen mode.

2. Hide the window.

3. Show the window again.

4. Repeat steps 2 and 3 multiple times.

Expected Behavior
The window should remain in its original fullscreen position when shown again.

Actual Behavior
Each time the window is shown, it shifts slightly outside the screen.

Has anyone experienced this issue before, or is there a known workaround?
