LWJGL should be updated to support Wayland windowing system. #63

Open itaibh opened 2 years ago

itaibh commented 2 years ago

I installed adventure-editor on Ubuntu 22.10 with Wayland windowing system. It fails to run with this exception:

$ flatpak run com.bladecoder.adventure-editor

This tells me 2 things:

  1. The LWJGL version used is 2.9.3. Checking in the LWJGL website I found it under "legacy", with the latest version being 3.3.1 as of to writing this report.
  2. The setup is looking for the X windowing system. I am not familiar with LWJGL and don't know if legacy version 2.* supports EGW but according to this issue reported in LWJGL the latest version needs special handling to support EGL, so make sure to try to find out which one is the better to use.
