title: Circle appears as a Triangle in Arcade python library
body: <p>I have been trying to draw a simple <strong>circle</strong> using the arcade python library, but all I can see is a perfectly positioned <strong>triangle</strong> instead.</p>
  <p>Here's the sample code I used:</p>
  <pre><code>import arcade
  
  # Set constants for the screen size
  SCREEN_WIDTH = 400
  SCREEN_HEIGHT = 400
  SCREEN_TITLE = &quot;Happy Face Example&quot;
  
  # Open the window. Set the window title and dimensions
  arcade.open_window(SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_TITLE)
  
  # Set the background color
  arcade.set_background_color(arcade.color.WHITE)
  
  arcade.start_render()
  
  # Draw the face
  x = SCREEN_WIDTH // 2
  y = SCREEN_HEIGHT // 2
  radius = 100
  arcade.draw_circle_filled(x, y, radius, arcade.color.YELLOW)
  
  arcade.finish_render()
  
  # Keep the window open until the user hits the 'close' button
  arcade.run()
  </code></pre>

  <p>After several hours of searching the internet for a solution, I tried it on another PC, and I got a proper circle !!</p>
  <p>My machine spec:</p>
  <p>i) AMD Ryzen 5 2500U , Vega 8 graphics</p>
  <p>ii) 8 GB RAM</p>
  <p>iii) OS: Ubuntu 21.10</p>
  <p>iv) Python version: 3.10</p>
  <p>The machine on which it worked also runs Ubuntu 21.10, with an AMD CPU + GTX 1060 6 GB video card and has Python 3.10 installed.</p>
  <p>What could be the problem?</p>
