view dock switching changes opengl context, and sometimes may crash

[miyanyan]

Describe the bug (both Chinese and English are OK)

When click dock switch button, and select "view", the editor exit

Environment

• System: Windows 11
• Zeno Version: latest

when switch dock:

• new DisplayWidget -> new ViewportWidget
• since ViewportWidget is derived from QGLWidget, initializeGL will be called
• in initializeGL, the context has been changed, the pre one is ctx1, now is ctx2.

  void ViewportWidget::initializeGL()
  {
    OpenGLProcAddressHelper::ctx = context();
    Zenovis::GetInstance().loadGLAPI((void *)OpenGLProcAddressHelper::getProcAddress);
    Zenovis::GetInstance().initializeGL();
  }

• in Zenovis::GetInstance().initializeGL(), first call Session::~Session(), it want delete the opengl things in ctx1, but now is in ctx2, so delete shader CHECK_GL(glDeleteProgram(pro)) will raise an error GL_INVALID_VALUE

  void Zenovis::initializeGL()
  {
    session = std::make_unique<zenovis::Session>();
  }

  So what is the usage of existing two same dock widgets, it seems that we just need to change the dock widget position when switching dock

I got the same error on Linux,
