Bug 933075 – games-emulation/ryujinx-1.1.1221: crash if the environment variable GDK_BACKEND is set to "wayland" on wayland systems.

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Xuesong Yan 2024-05-28 15:52:36 UTC]

Ryujinx is not a native wayland application. Indeed, there is a open issue on their github repo (https://github.com/Ryujinx/Ryujinx/issues/5566) on the request of native wayland support. 

Even the environment variable GDK_BACKEND is set to "wayland", the emulator can boot games without problems. However, UI interactions might crash the emulator.

Reproducible: Always

Steps to Reproduce:
1. export GDK_BACKEND=wayland
2. run the Ryujinx.sh
3. right click a game in your game list, select "Manage DLC"
4. left click the "Add" button in popup window
Actual Results:  
The emulator crashed with following outputs on terminal,

"

"

Expected Results:  
The emulator should not crash.

I suggest the Ryujinx.sh should be modified to enforce the program running under 
Xwayland/X11 environments until the upstream closes the issue "https://github.com/Ryujinx/Ryujinx/issues/5566". Inserts a line "export GDK_BACKEND=x11" into the script should be enough to fix the problem.

Does this work correctly with GDK_BACKEND=x11 ?

Please report that the described interaction crashes the emaulator also on the Github issues as that issues only mentions **warnings** thrown by the app.
