Xwayland crash when alt tab/mouse leaving screen

[jamjamjam]

Hello

I am running into issues with wayland and wesnoth crashing while running under xwayland (I assume that's how it's running anyway) since updating Fedora KDE to the latest version where wayland is enforced. This issue was not present before when I was running under X11, and occurs when swapping focus away from wesnoth and back (detailed steps below). If nothing else takes focus it works fine, and either way also only crashes when in the scenario not the main menu which is fine with alt tabbing. Seems to be related to the mouse but that's just a guess, so maybe not happy with how mouse access works in wayland?

I'm open to this being a packaging issue of course - if so I'll need to go bug the maintainer - and as stated with the same hardware and distro (granted 39 not 41) it worked fine so wayland (and thus xwayland) are the only notable change which, combined with the fact the graphical output dies but the audio keeps running, really points towards that being the cause. I am using some very low level configuration to rebind some mouse buttons because of the annoying way wayland words so that might be involved too as it does seem to be the mouse that drives this problem.

Operating system, including its version; and Wesnoth version, including the configured language.
OS: Linux, Fedora 41 (KDE Plasma) x86_64
Wesnoth: 1.18.2 x86_64

If you installed Wesnoth from a Linux repository using the terminal, make sure that you downloaded the full package that includes all campaigns and music.
Yes

A step-by-step walkthrough of how to reproduce the problem. If the problem cannot be reproduced, our ability to identify its cause and fix it will be severely limited.

1. Start game
2. Start any campaign (stock and custom tested)
3. Campaign loads fine and works fine
4. alt tab out and back in (if fullscreen)/move mouse out of window, click outside of window then return to window (when running windowed) - seems fine if you just move the mouse out and don't click elsewhere. Also other program notifications that take focus seem to cause it.
5. game runs very slowly for a few second, then freezes and then the output goes away/crashes: audio continues to play until remaining process(es) are manually killed. Sometimes the output goes greyscale first too. Feels like it suddenly spikes in resources or something

What I've tried to fix it that hasn't worked:

• fullscreen
• windowed
• vsync on/off
• adaptive sync on/off on monitor
• animations on/off
• limit fps on/off
• custom campaign vs stock (feels like stock might last 4-5 seconds longer without crashing, maybe because smaller maps)

Locate the game logs and include them in your post, either in a code block or (for large/long logs) a file attachment.

For what it's worth my logs were located in userdata and trying to output to file as was suggested in the forum thread didn't work. Either way they weren't particularly enlightening I don't think.

Probably same as https://github.com/wesnoth/wesnoth/issues/7601.

Probably same as https://github.com/wesnoth/wesnoth/issues/7601.

Yup that looks very similar, I'm not getting the explicit error message reported there but I'd imagine it's related and possibly I'm just missing some sort of verbosity/debug mode flag to output the error. I'm also running AMD rather than Nvidia but it seems like that's not a factor.

If there's a good way for me to hunt down better debug information and that'd be of use I could provide that, otherwise I'm happy to hang on and wait for a fix.

I tried running with --log-debug=all and the game barely functions and guessing for domains other than all is shooting in the dark a bit.

[jamjamjam]

I managed to get it to run with debug=all by directly loading into a campaign on the commandline with -c (as otherwise it froze while loading unit details).

The resulting log is 1151287 lines long and doesn't have an obvious failure point since as I said the game seems to keep running with audio playing until I manually kill it from the terminal (ctrl+c or otherwise) but if that's likely to be useful I can try and provide it. It comes out to something like 75MB though so maybe I will have to upload it somewhere else.

And wouldn't you know it there's our friend the Broken pipe just like the github issue suggests! There's a huge block of these SDL_TEXTINPUT messages around it if that helps at all.

I think I have this bug too, but I am on Fedora 43.

I tried the flathub flatpak which is currently on version 1.18.5, and it wasn't crashing for me.

I was not even aware it is possible to play wesnoth on xwayland already. Guess I have to try
this eventually. Are there many wesnoth developers testing on wayland?
