Description

My personal project, dim (packaged as dim-screen), uses the Smithay Client Toolkit to access the single pixel buffer manager (spbm) global and covers the screen with a certain opacity black in order to dim the screen, but it seems newer versions of Hyprland fail to give it access to said spbm global (due to wlroots fork?).

This did not occur in Hyprland v0.36 through v0.39 (didn't test v0.40) but fails on both v0.41.1 and hyprland-git (using solopasha's COPR).

Here is the issue for reference (on my comment with better stacktrace): single_pixel_buffer_manager_v1 error on new Hyprland v0.41

I am not sure if this would need a fix in Hyprland or the Smithay toolkit/wayland-protocols Rust crates. (Or, I am just doing something incorrectly)

How to reproduce

Install the dim package (see installing), or preferably for a better stacktrace, build dim from master, and attempt to run it with RUST_BACKTRACE=full. See panic because wp_single_pixel_buffer_manager_v1 is NotPresent.

Forgot to add: works on Sway 1.9, and river 0.3.3 (latest of both)

yes, single pixel has been dropped. It will be reimplemented in the future.
