high CPU and error: Reference element is not the same element for which references were queried [Plugin: GLSL] about glsl4idea HOT 5 CLOSED

That might be a bug in this plugin. Could you please share a file that causes that problem? If you want, you can do it privately, my e-mail is public. I'd appreciate it if you send a minimal file that still reproduces this problem. I don't have much free time nowadays, so simple repro will massively increase the chance of me fixing it. Thanks!

This is caused by the messy reference-handling implementation of the plugin. Fixing it will require a partial rewrite/refactor of the reference handling code. In particular, getReferenceProxy needs to go away and elements that actually are references must create the references from themselves, not through the proxy, because IDE asserts that this exact thing does not happen.

Unreliable repro:

attribute highp vec2 aVertPos;
    attribute mediump vec3 aVertCol;

    varying mediump vec3 vVertCol;

    uniform highp mat4 uModelViewProjectionMatrix; // Rename this variable to something else

    void main() {
      vVertCol = aVertCol;
      gl_Position = uModelViewProjectionMatrix * vec4(aVertPos, 0.0, 1.0);
      //gl_Position = vec4(aVertPos, 0.0, 1.0);
    }

Is there a plan to fix this?

Should be fixed by c0a3b30 and following commits.
