QLineEdit cannot copy text from clipboard

1. Issue description:  The sub interface of clicking buttons through the main interface cannot directly paste text

2. Issue phenomenon:  issue-video.mp4

3. Issue detail:  

   (1) Click on other areas with the mouse, and then click on the sub interface. This way, you can paste the text

   (2)  AMD architecture no issue,

         ARM architecture and XCB environment no issue

         ARM architecture and Wayland has issue

   (3)  The text copied from QLineEdit in the sub interface can be pasted

4. Issue analysis:

    I don't think this problem is caused by Qt, it may be related to Wayland and the system clipboard

    But I know where to investigate, and I hope you can guide me. Thank you
