sway resizes floating windows back to their old size

[the-isz]

Hi sway developers/community!

While writing a GUI application that resizes its window programmatically, I came across the following... weirdness:

When moving the mouse cursor out of a floating window's area, sway sends a resize event to the window, resizing it back to its original size.

I'm not sure if this is by design or an actual issue.

I have created a minimal reproduction program including a step-by-step guide in this gist.

$ swaymsg -t get_version
sway version 1.4

Thanks for looking into this and for gifting the world (including me) with this brilliant window manager!

Best regards

Thanks for the concise reproduction! Running it on my system with debugging on shows:

This sounds like it'd be a wlroots issue. sway sends [email protected](102, 50, array) when the window is left, where GNOME sends [email protected](400, 400, array) and the issue doesn't manifest.

Glad I could give something back :)

Let me know if you need more information or if I can help some other way.

Getting really annoyed by this myself. I think the behavior from i3 should be maintained on floating windows.

what's the status of this issue? I can reproduce the same thing with my experimental wayland Godot branch.
