crash with stacktrace

[shumvgolove]

Running the Helldivers 2 spawns two windows (the game window and I guess the tray icon), where quickly switching between them results in a crash:

[nekopsykose]

does this happen on the latest main? there was quite a few bugfixes since the last release and no new release yet

[shumvgolove]

I'll try to reproduce from latest commit.

[Supreeeme]

Were you able to reproduce on latest?

Compiled from https://github.com/Supreeeme/xwayland-satellite/commit/95afa163a60167cd97bf6afa870bc117a1be3d03 commit, can reproduce when somewhat quickly resizing the Steam window:

I assume it's a Xwayland crash, not necessarily xwayland-satellite?

[Supreeeme]

Hard to tell from just that, could you give the whole log? Also, what compositor is that?

[shumvgolove]

Here's the full log: xwayland-satellite.log

Compositor is niri 0.1.7

[Supreeeme]

You're resizing the window via the little thing on the Steam window? I'm curious as to why that is even working, because as far as I know it shouldn't...

[Supreeeme]

Reopen if this is still seen.
