[Bug 2152124] [NEW] Hard crash of Wayland session (back to login/initramfs screen) when scrolling emails in Thunderbird.

You have been subscribed to a public bug: When using Thunderbird under Wayland on Ubuntu 26.04 (Intel GPU, ASUS Zenbook UX310UA), pressing the Up/Down arrow keys to scroll through emails causes an immediate and hard crash of the GNOME Shell / Wayland compositor. The system drops connection to xwayland and crashes back to the disk decryption/login screen. The issue is 100% reproducible on Wayland. Workaround: Switching the session to "Ubuntu on Xorg" completely resolves the issue and Thunderbird works normally.
