(GDX-Liftoff crashing FIXED) Missing custom rocket logo on KDE 6 Wayland

[akkanben]

There appears to be an issue with configuration or implementation of GLFW in GDX-Liftoff 1.13 with regards to Wayland. I am able to launch the configuration tool if I login to my system with X11. I can also successfully launch the tool's previous version 1.12.1.17.

Interesting. For me it loads and seems to work properly, though I get all those errors in the terminal except the first one.

Seems the EGLDisplay error may be an NVIDIA specific issue (my system uses an AMD GPU)? Try setting the environment variable detailed here when running the jar: see wired-tomato/WayGL#1 (comment) and glfw/glfw#2510

As for why the previous version works, it may be due to LWJGL3 being updated from 3.3.3 to 3.3.4 since 1.21.1.17

Thank you for the tip! Setting __GL_THREADED_OPTIMIZATIONS=0 avoids the crash for me during launch. Like you mentioned I also still see the GLFW feature unavailable errors but the EGLDisplay error is gone.

A couple minor issues I still see (that are not present when I use 13.0 under X11 or 1.12 under Wayland) are:

1. The custom gdx-liftoff icon is not visible
2. Resizing the window is very laggy.

That said, I'm going to presume the root cause here will get ironed out with future Nvidia driver updates. Closing the issue, just let me know if there is any other reason to reopen.

[SonicGDX]

Hmm, resizing the window seems to have higher latency but is smoother on 13 for me, but like you the custom icon is not visible on 13 for me while it is on 12. I think the issue might be worth reopening for that (though maybe with a changed title), as that seem to be a regression for Wayland in general rather than an NVIDIA specific issue

[SonicGDX]

Also @tommyettinger it might be worth mentioning the NVIDIA issue and associated fix somewhere in the documentation, as it may take some time for NVIDIA to fix the driver issue

[akkanben]

Reopening this to address the remaining issue related to the missing GDX-Liftoff logo. Like previously stated the logo is visible under X11 with release 13.0 or under Wayland with earlier releases like 1.12.1.17.

[tommyettinger]

So I don't think I even know what Wayland actually is; I have only seen compatibility issues with it. I didn't really follow what the steps are to resolve an unclear bug with some kind of system I'm not familiar with. If I edit the README.md myself to mention this, expect it to be horrifically mangled and loaded with inaccuracies. PRs welcome!

I don't really think the logo (did you mean icon?) missing from a setup tool affects generated projects, unless I'm understanding this wrong. If you're using Linux you have to be used to some apps looking wrong... Or not looking at all, if they're purely CLI. The logo or icon missing may simply be part of LWJGL 3.3.4's various changes, which I can't do much about. I might have removed the icon setting code in some launchers because there were issues with loading assets from the folder they are normally in. I don't really remember. That may have been in my own projects.

[tommyettinger]

Can anyone verify if this is an issue with 1.13.0.1 ? It downgrades the version of libGDX that Liftoff uses to 1.12.1, which seems to work better on Wayland.

It's not an issue with 1.13.0.1 yeah. It behaves the same way as Liftoff 1.12.1.17
