In my project, I have two main pages: 'index' and 'about'. The 'about' page includes a cool animation that you can check out here.
The issue I'm facing is that when I navigate from the 'index' page to the 'about' page locally, the frames per second (fps) of the animation seem to fluctuate:
Initial visit to About page:
52.9 fps
When going back to Index:
41.0 fps
Returning to About:
29.5 fps
I am unsure about what could be causing this issue. Just for context, the project is built using Vue.
An error message appeared in the console:
Too many active WebGL contexts
I believe it might not be best practice to create a new renderer and redo all the work for each mount?
I experimented with keeping the component alive, and that seemed to resolve the issue.
<keep-alive>
<router-view/>
</keep-alive>
Alternatively, you could consider moving the renderer up to the parent component and reusing it instead of creating a new one for each mount.
On another note, I recommend trying out the extension PixiJS Inspector. It's great for PIXI debugging purposes. It also reveals that every time "About" is clicked, a new PIXI container is generated. By implementing the aforementioned solution, only one container will exist throughout user interactions.
