Bug description:
  [ Impact ]

  Just upgraded to Ubuntu 24.10 which comes with egl-wayland 1.1.15, now
  qmapshack crashes on start:

  QSocketNotifier: Can only be used with threads started with QThread
  qmapshack: ../src/wayland-eglsurface.c:2562: wlEglDestroySurface: Assertion `wl_list_empty(&surface->ctx.streamImages)' failed.

  It seems to be this upstream bug in egl-wayland: https://github.com/NVIDIA/egl-wayland/issues/127
  It was fixed upstream: https://github.com/NVIDIA/egl-wayland/pull/131

  The fix was released in 1.1.16. The changelog says it fixes crashes in
  Qt6 webengine, but it looks like qmapshack uses Qt5. So maybe it
  affects Qt5, too.

  Other software seems to be affected in Ubuntu, like akregator:

  [ Test Plan ]

  1. Set up a machine with an NVIDIA GPU running Ubuntu Deskto 24.10
  2. Log-in to a Wayland desktop session
  3. Open QMapShack
  4. Verify that the application launched correctly
  5. Verify that you did not receive a crash report prompt

  [ Where problems could occur ]

  egl-wayland implements the OpenGL Wayland extension for NVIDIA
  proprietary drivers. It is only used on systems with at least one
  NVIDIA GPU, and it is a critical component for those systems (Ubuntu
  Desktop 24.10 defaults to Wayland)

  A problem with this patch would manifest as the Wayland desktop not
  loading, or individual applications not displaying or crashing.
