Temporary Solution (Downgrade to v0.34.0 again…)

Open up a TTY (CTRL + ALT + F3)

Check if you have the previous version cached

ls /var/cache/pacman/pkg | grep hyprland

Downgrade to hyprland-0.34.0-1

sudo pacman -U /var/cache/pacman/pkg/<previous-version>

Now restart hyprland or (CTRL + ALT + F2 -> Login)

This solved it for me, hopefully there is something i can do in order to make v0.35.0 work, but until then. i will be stuck on this version.

The segfaul is in src/render/Renderbuffer.cpp:55 because of throwing in constructor

    if (glCheckFramebufferStatus(GL_FRAMEBUFFER) != GL_FRAMEBUFFER_COMPLETE)
        throw std::runtime_error("rbo: glCheckFramebufferStatus failed");

The previous commit passed this check for some reason.

Update:

Changing

RASSERT(PWLREGLCREATEIMAGEFROMDMABUF, "wlr_egl_create_image_from_dmabuf was not found in wlroots!");

RASSERT(PWLREGLCREATEIMAGEFROMDMABUF != null, "wlr_egl_create_image_from_dmabuf was not found in wlroots!");

does not trigger the segfault. The only reasonable explanation is that the “evil hack” is somehow UB.
