[Bug 1967659] [NEW] Qt apps broken on nVidia/Wayland (Event thread blocked)

[Launchpad Bug Tracker]

You have been subscribed to a public bug by Rik Mills (rikmills):

Qt apps (particularly those using QtQuick) — including the KDE Plasma
desktop — are broken on nVidia/Wayland systems since the nVidia egl-
wayland library was updated to 1.1.8.

https://github.com/NVIDIA/egl-wayland/issues/40

The fix for this has landed in upstream Qt:
https://codereview.qt-project.org/c/qt/qtwayland/+/301712

But backports from upstream Qt are heavily delayed to non-commercial
users.

The KDE project has backported the fix to their branch, and there is a Merge Request available in debian:
https://salsa.debian.org/qt-kde-team/qt/qtwayland/-/merge_requests/5

Without this fix, KDE Plasma is totally unusable under Wayland, and some
Qt applications will likely break under Gnome, too, which could be a
problem if nVidia/Wayland will be the default for Gnome in 22.04.

Most other distros have either backported this fixed, or switched to
packaging the KDE-maintained branch of QtWayland, which contains it.
