[deguilardi]

• cocos2d-x version: 3.16
• devices test on: emulator pixel 2xl
• developing environments
  • NDK version: r16b

Steps to Reproduce:

1. Call ParticleSystemQuad::create( "ANY_PALIST_FILE" );

You will see a black screen and a bunch of the error below every second

fixed before 3.17 release, at #18606

On the latest commit (29 september 2018) and NDK 18 the issue is still exists.

What is your cocos version?

I've also this kind of black screen with cocos2d-x 3.17 / ndk 16b / compile & target sdk 22 / tools version 27.0.3 / Android Studio 3.2.1 - on x86 emulators and due to a ParticleSystemQuad.

I'm getting this on a regular android test device in cpptest cocos2d-x 3.17.
Goto UVAnimation test and then do something that will cause the activity to be rebuilt (I found this while changing my devices language to test localisation). Now reopen cpptest and most objects that use a custom material will be black. OpenGL error 0x0502 is getting spammed in the log.

I am also seeing this in 3.17. Switching the Emulated Performance -> Graphics from "Automatic" ("Hardware - GLES 2.0") to "Software - GLES 2.0" works around this problem for me. Albeit, the performance is degraded significantly.

I'm getting the same error repeating itself in the log when trying to use an emulator. I've only been able to create a new cocos project that works by default once.

same here using 3.17. dont know what the cause . try to undo, but still not fixed

Using 3.17.2 also encounter this issue, after investigated it was caused by

OpenGL error 0x0502 in ... removeVertexArrayObject: ERROR: cannot delete VAO 0!

Within CCParticleSystemQuad.cpp line 550 is trying to delete vertex array object which does not exist.

if (_VAOname)
{
glDeleteVertexArrays(1, &_VAOname);
GL::bindVAO(0);
}

[deguilardi]

This is awesome you found the root of this. Could you work it around?
