[Bug]: Memory leak

[greydot]

Describe the bug

Just that. Huge memory leak when viewing the main timeline. Both v0.6.3 and the latest git (1ffa7cd) are affected.

Steps To Reproduce

1. Open Tuba
2. Scroll down continuously, regardless of how fast everything loads
3. Observe the leak

Thanks for the report!

Just to make sure, this is the main/"Home" timeline right?

If that's so, that's unfortunately expected. The TL:DR is #798 (comment) but here's another: Due to the lists used in timelines, nothing gets freed based on scroll position, but the current alternatives have other limitations and issues.

If that's the case then I'll close this, since it doesn't add anything to the already open ones on this matter

Yes.

Due to the lists used in timelines, nothing gets freed based on scroll position, but the current alternatives have other limitations and issues.

I mean, sure. But a gigabyte of memory just to store a hundred or so posts? That's a bit of a stretch, isn't it?

Maybe, maybe not. Nothing comes for free, complex widgets, images, network cache, websockets, json deserialization, html to native widgets convertion... are some of the many layers a timeline is under, it's not just 'storing a few posts'. Per the linked issues, the ideal solution is to move to a recycler list, like ListViews, so everything gets destroyed and freed as the scrolling position changes.

If you manage to find areas where the current implementation can improve, let me know! In the meantime, I'll go ahead and close this issue as it doesn't provide anything new
