plasmashell segmentation fault (signal 11) on KDE Neon Wayland session

Goal: assess whether the experimental Wayland session in KDE Neon can serve as a stable base for a repeatable development environment when using NVIDIA proprietary drivers.

Constraint: the Wayland variant is marked experimental, and users with NVIDIA drivers frequently observe plasmashell crashes reporting a segmentation fault (signal 11), with no consensus on readiness.

Uncertainty: it remains unclear under which specific conditions the fault occurs, whether any configuration tweaks mitigate it without reverting to X11, and how the choice influences reproducibility of GUI‑based tests.

What specific driver or kernel versions trigger the plasmashell segmentation fault on Wayland?
Are there interim work‑arounds that allow Wayland to be used reliably for development without switching to the X11 ISO?
How does selecting Wayland versus X11 affect the consistency of automated GUI tests in a repeatable Neon‑based environment?
