Crash when joining Arena, QUnhandledException

[Mistra]

I'm using version 10.0, AppImage
I'm opening an arena at hero selection panel when the Tracker crashes. The installation is fresh, brand new.

Here are some logs

11:33:58 - GameWatcher(3): New arena: choosing heroe.
11:33:58 - DraftHandler: Begin hero draft.
11:33:58 - GameWatcher(4): Found SetDraftMode - DRAFTING.
11:33:58 - DraftHandler: No continue draft because already drafting or no hero.

11:33:58 - GameWatcher(29): LoadingScreen: GAME_MODE -> DRAFT
11:33:58 - GameWatcher(29): Entering ARENA (loadingScreenState = arena).
11:33:58 - DeckHandler: Enter arena
11:33:59 - DraftHandler: Hearthstone arena screen NOT loaded from settings.

Let me know if there are any other infos I can give, in case you want to dive in.

cant help, sorry

Uhmmm, meanwhile I was trying to download the source and debug it myself but this comment isn't encouraging.
May I know why, out of the blue, you are basically suggesting there's nothing to do?

[supertriodo]

I'll help, it's just I cant reproduce it myself.

[Mistra]

Ok, if you are still in.

I managed to understand something is happening when you call line 1974 @ DraftHandler.cpp
ScreenDetection screenDetection = futureFindScreenRects.result();

The debugger stops at d.waitForResult(0); of QFuture

I understand there's something that... breaks the promise/future? Sorry It's been years I don't touch C++, let alone QTish C++

Does it ring any bell there? This afternoon I'll keep diving in, it's fun!

It turns out, that call somehow asks the w-server something (coordinates?). To draw the big dots with the card score if I understand right.
The issue here seems to be QT related, I use Wayland on GNOME. Infact when I switched back to X everything works fine. I'll see if I can manage to catch that unhandled exception or understand more why with Wayland the framework doesn't work.

I see, I haven't yet tested AT on wayland.
