Description

Running Xwayland rootful crashes with the following logs when the mouse moves within the window.

Xwayland:

XWAYLAND: wl_display@1: error 1: invalid arguments for wl_shm@4.create_pool
(EE) failed to dispatch Wayland events: Invalid argument
X connection to :3 broken (explicit kill or server shutdown).

Hyprland:

Any GTK app that i tested triggers the crash. Xterm for some reason doesn’t.
