Fatal error trying to start adventure mode on linux desktop

[jmelesky]

Describe the bug When running forge-adventure.sh from the command line, the splash animation appears, a blank window appears, and then the program crashes with a SIGSEGV:

I tried this with dailysnapshots from 10.22 and 10.23. I tried this with both Oracle JRE 21.0.5 and OpenJDK JRE 1.21.0. Non-adventure mode starts up without a problem.

All drivers are up-to-date. Graphics are Intel Mesa integrated, nothing fancy.

Desktop (please complete the following information):

• OS: Pop!_OS 22.04 LTS
• Version: 2.0.00-SNAPSHOT-10.23 daily snapshot

Additional context Happy to try other JRE versions or different java launch configurations if you'd like.

@jemelesky can you try to redownload 10.24 snaps or the next snaps if the issue persists on your end?

[jmelesky]

Tried with the 10.24 snap, and it got further (displayed the "Welcome to Forge" splash screen), but still segfaulted:

anyway how do you run the app? do you use java -jar command or the forge-adventure.sh?

[jmelesky]

I use the provided forge-adventure.sh. I'm happy to try other ways of launching if you'd like.

Can you try to update your graphic driver? Are you using MESA driver?

[jmelesky]

I'm using the drivers provided with stock Pop!_OS 22.04 LTS, which I believe are MESA. I've been updating daily in case that fixes things, but no luck so far.

Ok I think I found the issue, the natives are not updated for the mobile build but I'm not really sure if those will fix your issue since they work on windows.

[jmelesky]

I'll give it a try when the next daily snapshot comes out.

It didn't get as far this time:

Does the release 1.6.65 version works on your end? If thats the case then it should be something on the newer libgdx engine.

[jmelesky]

Good idea. The instructions say to go with the snapshots for Adventure mode, so I hadn't tried it. But just downloaded it and it gets to the menu screen without a problem.

Ok maybe the small splashscrreen crashes on your end since I found this single issue similar with yours..

Just want to say that this is the exact same issue I had here: https://github.com/Card-Forge/forge/issues/6415.
