pkgs/development/libraries/qt-5/modules/qtwayland-app_id.patch

   1 Ensure that the correct `app_id` for Wayland is set. The upstream implementation
   2 uses `QFileInfo::baseName()`[1] which strips everything away after the first dot.
   3 This means that `.foo-wrapped` has an empty `app_id` because `baseName` returns
   4 an empty string in this case.

   6 The patch basically checks whether the program has the form `.foo-wrapped` (i.e. got
   7 wrapped by `makeWrapper`) and if that's the case, `foo` will be the correct `app_id`.
