Background

I have encountered a problem just ran the early stages of the Roguelike tutorial, specifically the two initial map examples.

• 2.2. Walking A Map
• 2.3. A More Interesting Map

To be sure, I've downloaded the source from the github example:

• amethyst / rustrogueliketutorial

Problem

• Running both examples run the mouse moves the 'player' around the screen OK
• If the mouse is moved, we get this error as shown.

Error

Set-up

The tutorial version was using earlier builds of the rltk and specs. I reconfigured the toml file, ran cargo update to test with the newer versions (see below), same problem.

Cargo.toml

[dependencies]
##  rltk            = "0.8.0"
    rltk            = "0.8.7"
##  specs           = "0.17.0"
    specs           = "0.20.0"
    specs-derive    = "0.4.1"

LSB

The error seems to be with the Mesa 3D graphics using Wayland on Kubuntu 23.10.

 $ lsb_release -a

Summary

• For others, this only seems to happend if you touch the mouse. So don't touch the mouse ;-)
• I was wondering if there is some way to configure the RLTK to avoid the problem or to just use a more basic graphics layer
• Also, does anyone know how to get logs or investigate this:
  libEGL warning: egl: failed to create dri2 screen problem?

Suggestions welcome.
