Wrong colors on Cairo renderer #3627

Closed Batres3 closed 7 months ago

Batres3 commented 7 months ago

Description of bug / unexpected behavior

Running the quickstart example in the wiki generates wrong colors (using Cairo renderer)

Expected behavior

The colors are supposed to be a black background and a pink interior, as generated with the OpenGL renderer, which works fine

How to reproduce the issue

I'm running in a virtual environment, the following is the exact code I'm running using manim -pqh presentation.py --renderer=cairo CreateCircle, presentation.py being the name of the file.

Code for reproducing the problem ```py from manim import * class CreateCircle(Scene): def construct(self): circle = Circle() # create a circle circle.set_fill(PINK, opacity=0.5) # set the color and transparency self.play(DrawBorderThenFill(circle)) # show the circle on screen ```

I cannot reproduce your problem... you should not need to use renderer=cairo since this is the default setting, but with and without everything renders just fine on my system... On the other hand I don't know your operating system, but if this was a general problem in Manim it would have been reported a long time ago.

Could it be a problem with your video player? Try to watch the generated .mp4-file with a different viewer.

Also: do you get the same result when you let Manim just generate a static image using the following code:

class CreateCircle(Scene):
    def construct(self):
        circle = Circle()  # create a circle
        circle.set_fill(PINK, opacity=0.5)  # set the color and transparency
        self.add(circle)  # show the circle on screen

Wow, you're entirely right, apparently Totem, the default video player in PopOS! has some issues. I never would've thought of that, thanks, I changed it to VLC and it works like a charm.
