    Description

      Linux Ubuntu 22.04.4 / Wayland

      Qt Creator 14.0.1

      Device: Raspberry Pi4 64 bit with Qt 6.8.1

      Steps to reproduce:

      1. Run widgets camera app on RPi4 device using wayland-egl platform.
      2. Change the tab to Video
      3. Click 'Record' button to start recording
      4. After a while click and hold right mouse button on the windows and move the mouse

      Expected: The video is recorded.

      Actual: The app hangs and only relaunch could help. Additionally, when holding the windows with the right button it starts rotating - it looks like some transformation issue. See more on the attached video.

      Reproducibility:  100%
