Code I believe to be relevant
class StoryView(arcade.View):
def __init__(self):
super().__init__()
arcade.set_background_color(arcade.color.BLACK)
self.camera_gui = arcade.Camera()
self.background = arcade.load_texture("assets/main_menu/columns.jpg")
def on_draw(self):
self.clear()
self.camera_gui.use()
arcade.draw_lrwh_rectangle_textured(
300, 0, self.window.width - 300, self.window.height, self.background
)And
class OtherView(arcade.View):
def __init__(self):
super().__init__()
arcade.set_background_color(arcade.color.BLACK)
self.camera_gui = arcade.Camera()
self.background = arcade.load_texture("assets/story/happy_mort.jpg")
def on_draw(self):
self.clear()
self.camera_gui.use()
arcade.draw_lrwh_rectangle_textured(
300, 0, self.window.width - 300, self.window.height, self.background
)Conversation from Einarf in help channel 3
Per Einarf - "I thought I fixed the clear() method. Optionally just specify a viewport that covers the entire screen when you clear it.0, 0, w, h ... but I thought I changed it to clear the entire screen unless you pass in a viewport. Because this is the lesser evil. What you are seeing is the front and back buffer showing uncleared contents as the frames are swapping"
