Bug
Description
At complete random (theres no pattern), when i have a Jetbrains tool open (eg. Rider), multiple of my apps (Rider, Ghidra, and WebCord) will be brought down. WebCord closes with no extra information (exit code 1), but it seems to maybe dump some things into dmesg (maybe unrelated?), Rider and Ghidra dont seem to dump any logs anywhere relating to the error, they act as if they were closed normally

This is maybe related to XWayland, as those are the only apps of mine that are running under Xwayland
Important to note this does not happen on compositors such as kwin_wayland
How to reproduce
Open a Jetbrains tool such as Rider alongside WebCord, then just interact with either software for awhile, at random (sometimes after as much as 10mins), both apps will be brought down at the same time (WebCord is running under xwayland on my system)
Crash reports, logs, images, videos
hypr logs logs.tar.gz
that would suggest xwayland crashed. I don't think this is an issue with hyprland. Have you tried testing on sway-git whether it happens there too?
Another note, your hyprland version is very old.

I'll try sway after trying updating hyprland, it seems the hyprland in the arch repos is extremely old, i didnt realize that
I havent gotten the webcord+rider crash yet, but i am now getting a weird rendering bug with the completions, where if the completions update without recreating the separate completions window, it shrinks more and more, didnt happen on the old version
(i used rider for an hour with no crashes of rider+webcord)
while i was writing this, it seems that the entirety of hyprland was brought down for some reason (kicked back to greeter), log folder from right after are here
and while i was writing that, firefox crashed when i tried to drag and drop a zip from dolphin, im going to assume thats a separate issue though
heres the coredump for hyprland from the above full crash to greeter hyprland.coredump.zip
edit: it just happened on latest hyprland, i'll try sway
after >2hrs of running both rider and webcord (using both constantly), the crash did not occur with sway, and it doesnt happen with kwin either
Would be nice to get an xwayland debug stacktrace or a log. Might be a protocol error. Running xwayland with WAYLAND_DEBUG=1 and inspecting the output when it crashes might also help.

how would i set env vars for XWayland? i glanced through the hyprland wiki and didnt see anything about running xwayland manually also i dont see xwayland in coredumpctl, so i dont think xwayland itself is fully explicitly crashing, so yeah might be a protocol error
https://gitlab.freedesktop.org/wlroots/wlroots/-/blob/master/docs/env_vars.md?ref_type=heads#wlroots-specific
wlr_xwayland
i put env = WLR_XWAYLAND,WAYLAND_DEBUG=1 Xwayland in my hyprland config, but now it seems that Xwayland hasnt started up at all (all xorg apps fail to open), i also tried creating a wrapper script which just has
#!/bin/sh
WAYLAND_DEBUG=1 Xwayland
then setting env = WLR_XWAYLAND,/home/beyley/xwayland_debug.sh
but that didnt work either, am i misunderstanding how this env var is supposed to work?
i get this output
_XSERVTransSocketUNIXCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeAllCOTSServerListeners: server already running
(EE)
Fatal server error:
(EE) Cannot establish any listening sockets - Make sure an X server isn't already running(EE)
update: just had it occur with WebCord, VSCode, and Chromium, all running under XWayland, were just brought down at once, seems to not be related to Rider at least
heres the current state of my scripts, which cause the above mentioned "cannot establish any listening sockets" error
when i remove the env line, xwayland works fine
env = WLR_XWAYLAND,/home/beyley/xwayland_debug.sh
#!/bin/bash
WAYLAND_DEBUG=1 Xwayland >> /home/beyley/xwaylandlog 2>&1
another update: i was doing work and noticed waybar crashed, so i restarted it from a terminal, and then almost all my open apps closed immediately after, with waybar just saying "media suddenly stopped" and nothing else of interest
this time it wasnt exclusive to x11 apps, every app but kitty closed, including anki, firefox, webcord, and vscode (but this could be a totallly different issue manifesting itself as a similar one)
I get this Xwayland crash on a regular basis and its damn annoying. It seems to be something to do with having something in the clipboard, then opening a file open/save dialog. Here are a couple of logs:
journal log: https://pastes.io/co3dwld8ub hyprland log: https://pastes.io/gvy6lct3c6
would be nice if there were some clear repro steps, I've not had xwayland crash even once. Copying, pasting, opening dialogs.

I really wish I could reproduce it at will but it doesn't always work when I repeat what triggered it. I'll try and see if I can.
I made a wrapper for Xwayland so i can dump its output to a file. The last 2 lines of the output are:
XWAYLAND: wl_display@1: error 1: invalid arguments for [email protected]_pool (EE) failed to dispatch Wayland events: Invalid argument

Could you send your wrapper script and how to set it up with hyprland? I've been unable to get one working
mv /usr/bin/Xwayland /usr/bin/Xwayland_orig
/usr/bin/Xwayland:
#!/bin/bash
d=`date +%s`
mv /home/me/xwayland.log /home/me/xwayland_$d.log
/usr/bin/Xwayland_orig $@ &> /home/me/xwayland.log
I may have made some progress. In my hyprland.conf i have: env = QT_QPA_PLATFORM,xcb. I have removed this and only set this up for apps that really need it instead of it being system-wide. If you have this set system-wide, try what I did. I'm not 100% sure yet if this fully works around the Xwayland crashes but so far I am unable to reproduce it the way I usually do.

Can confirm this is the issue i am getting as well, using your wrapper script, i have no consistent reproduction, but it happens multiple times a day
XWAYLAND: wl_display@1: error 1: invalid arguments for [email protected]_pool
(EE) failed to dispatch Wayland events: Invalid argument
does the solution i mentioned above apply to you? would be interesting to know if it makes a difference.

ive had multiple xwayland crashes without any QT apps open, so i dont believe it is relevant to me
i have found a semi-consistent reproduction, open Jetbrains Writerside, open this repository, open some document and start typing, consistently every time, in under a minute it will bring down xwayland
its always the same error inside of the xwayland logs
does not happen on plasma
also happens on my system on nixos, and never on plasma wayland happens often more if im playing buckshot roulette for some reason
last few lines of xwayland output
Errors from xkbcomp are not fatal to the X server
XWAYLAND: wl_display@1: error 1: invalid arguments for [email protected]_pool
(EE) failed to dispatch Wayland events: Invalid argument
is there a way to at least restart xwayland? this happens way too often
Still an issue for me. My only solution is to run apps in it as little as possible but there's always the fear that it will crash at a very important moment. I only use QT_QPA_PLATFORM=xcb if the app has issues without it.

Having the same error!!!
modifying hyprland configuration as below:
xwayland { # latest configuration # use_nearset_neighbor = true # force_zero_scaling = true # current configuration use_nearset_neighbor = false force_zero_scaling = false }That works for me. Maybe the different scaling between xwayland and wayland lead to this error. If crashing again, I will report.
Tried this, but still causes xwayland crash for me

Do you have a reliable way of reproducing the crash?
