I created a "Hello, Kivy" window but the text won't shows up
I used Pycharm64 & Python3.7 environment to run the code:

from kivy.uix.label import Label
from kivy.app import App
import kivy

# the minimum OpenGL version supported by Kivy:
kivy.require('1.9.1')

# defining app class:
class HelloKivy(App):
    def build(self):
        return Label(text="Hello, Kivy")

# running the window:
HelloKivy().run()

console log:

The output is just a black window, and the text is invisible

I have already posted the thread on StackOverflow:
https://stackoverflow.com/questions/6131...t-shows-up

Finally, I got the solution

- The issue was due to my old integrated intel-made graphics card, arising conflicts with my os, and kivy!

- It was very hard to troubleshoot as Kivy and OpenGL claims to work correctly while the issue is still there!

- I should either purchase a new graphics card or try installing unofficial graphics driver if available to make kivy work well in my pc.
