Description

Server crashes

if the actual size of the shared memory of "fd" is smaller than the one set in the call to wl_shm_create_pool, Hyprland server will crash when trying to dispatch the events.

I tried running the same program (you will find it below) in weston and instead of crashing, it gave an error saying "invalid size" or "error accessing SHM buffer".

How to reproduce

Please check this repo for a version that breaks Hyprland.

I tried to make it as reproducible and small as possible to show the problem directly.

Check the section called "Running the broken version" for a way to run the version that makes Hyprland crash.
