Wev crashes "Error marshalling request: Too many open files"

[bendi-github]

Issue description

When running wev to debug input events, the log gets filled up with

[09:     xdg_surface] configure: serial: 32353
[10:    xdg_toplevel] configure: width: 848; height: 330
                      activated tiled-left tiled-right tiled-top tiled-bottom

and eventually crashes

error marshalling arguments for create_pool: dup failed: Too many open files
Error marshalling request: Too many open files

Input events are still logged while the log is being spammed.

Version

0.23.0b3.dev350+g6ee02e5c

Backend

Wayland (experimental)

Config

Default, I just changed the modkey to `mod1` for testing

Logs

Nothing shows up, besides the usual warnings the default config throws on wayland

Required

• I have searched past issues to see if this bug has already been reported, and it hasn't been.
• I understand that people give their precious time for free, and thus I've done my very best to make this problem as easy as possible to investigate.

0.23.0b3.dev350+g6ee02e5c

that is a really old version, please test on the latest

[bendi-github]

git clone https://github.com/qtile/qtile.git
cd qtile
pip install .
pip install --config-setting backend=wayland . 

qtile-0.26.1.dev25+g29695c71

The issue persists. I tested a nested qtile instance in additon to starting it directly via sddm. I noticed when I launched wev in a nested session, it crashed faster when compared to a non-nested session.

I wonder if this is really a dupe of #4821, that we're leaking stuff when certain events happen, and in the wev model these things end up as file descriptors?

[jwijenbergh]

#4880 fixes this for me

I doubt it, this seems like a recent regression in git

Fixed in git
