    Description

      I tried to test a display port hot-plug event with a QT sample app (opengl-window).

      When i plugged out the display port cable twice, the QT sample app occurs a segmentation fault.

      My test environment

      • QT 5.14
      • weston-8.0 (backend-drm)

      Does anyone have the same situation as me?

      is it the QTwayland bug or something else?

      Could you give me some advice for hot-plug error?

       

      If you need more information, please ask me. 

      Thanks

      Best regards
