[ 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.
