Description

Once every couple hours of normal Unreal Engine 5.3.2 Editor usage, Hyprland crashes with an abort signal.

How to reproduce

It happens sporadically and unpredictably throughout usage of the program, but almost always during or right after an interaction with the application window.

Edit: It might be worth noting that my system feels otherwise stable and smooth during graphical workloads on both native wayland and xwayland

I am going to attempt to reproduce the issue again with a debug build of Hyprland in hopes to get more information out of a core dump. If that doesn't end up working I'm going to try and build with sanitizers and see if I get anything then.

I have been getting a similar crash on applications like rnote/inkscape with the newest version of Hyprland, but only when I have a drawing tablet connected to my system. Do you have a drawing tablet?

I don't, but that's interesting.

[vaxerski]

asan trace please https://wiki.hyprland.org/Crashes-and-Bugs/#building-the-wayland-stack-with-asan

[iamtimmy]

When I try to run an asan build from the tty, asan aborts it during init and there is no log output for it. I've tried acquiring the stdout from the tty, but I can merely get the build output, not the output of the run itself. coredumpctl shows there is no corefile.

I'll go back to the debug build and find time to reproduce it and get a better strack trace. Let me know if you have any ideas on the asan run, output could help a ton there.
