How to reproduce

Unknown. I can't test on Linux or with an AMD GPU.

hm, looks like the format table got fucked.

[vaxerski]

https://github.com/hyprwm/Hyprland/blob/ea2501d4556f84d3de86a4ae2f4b22a474555b9f/src/protocols/LinuxDMABUF.hpp#L33-L39

Is there something wrong here? I remember wlroots having some comment complaining about BSD.

I'm guessing this is some bsd issue.

[vaxerski]

generally from the log hyprland seems to collect the dmabuf formats correctly, but the table in linux-dmabuf is malformed.

Most of the logic is here: https://github.com/hyprwm/Hyprland/blob/811429bfd4a46f33c7788580f72038b0c3c1c2b1/src/protocols/LinuxDMABUF.cpp

and it was tested under nvidia, amd and intel (albeit on linux) and was working.

I'm seeing this issue once every couple hours of Unreal Engine 5.3.2 Editor usage on NixOS Linux with the latest flake from this repo. I'm afraid I can't share an entire log file because it contains too much personal info.

The crash always happens right after [ERR] [LinuxDMABUF] FIXME: surface feedback stub There's no crash log, the window manager just closes and takes me back to sddm.

Here's a snippet:

check coredumpctl, sometimes the crash report fails generating.

[ERR] [LinuxDMABUF] FIXME: surface feedback stub isn't a big deal.

[iamtimmy]

Thank you! Checking coredumpctl tells me that on all occasions today, the exit signal was SIGABRT. I'm new to Linux so I'll have to quickly learn how to extract additional information from this tool. (Wish windows had something similar to this now)

[vaxerski]

that looks unrelated and odd.

[iamtimmy]

I see. I apologize for crashing the Issue then, how should I proceed? I'm editing my config so it builds a debug version of Hyprland. Should I create a new issue?

[vaxerski]

I've seen this issue somewhere else, but nobody's ever been able to reproduce it. Maybe a make asan would shed some light: https://wiki.hyprland.org/Crashes-and-Bugs/#building-the-wayland-stack-with-asan

At any rate, yes, it's a different issue so a separate ticket should be opened

[jbeich]

After creating a separate issue maybe also hide your own comments here as "offtopic" per https://docs.github.com/en/communities/moderating-comments-and-conversations/managing-disruptive-comments
