Description
- Window 10 64-bit
- Python 3.8
- PySide 6.4.2
- PyOpenGL 3.1.6
When I close the window, I get an "Invalid operation" error in resizeGL() on the line with the glViewport() function.
```python
import sys
from OpenGL.GL import *
from PyQt6.QtCore import Qt
from PyQt6.QtOpenGL import QOpenGLWindow
from PyQt6.QtWidgets import QApplication
class OpenGLWindow(QOpenGLWindow):
def _init_(self):
super()._init_()
def initializeGL(self):
glClearColor(0.2, 0.2, 0.2, 1)
def resizeGL(self, w, h):
glViewport(0, 0, w, h)
def paintGL(self):
glClear(GL_COLOR_BUFFER_BIT)
if _name_ == "_main_":
QApplication.setAttribute(Qt.ApplicationAttribute.AA_UseDesktopOpenGL)
app = QApplication(sys.argv)
w = OpenGLWindow()
w.show()
sys.exit(app.exec())
```
