Bug Report
Describe the issue: I’m pretty sure I cleared my image cache 12h ago, after it was at 4GB, and I looked at it just now at 10GB. That’s at least 6GB in 12h, if not 10GB. I did do a bit of scrolling to test some things but it wasnt a lot by any stretch.
There’s definitely something that can cause the cache to explode in size. I don’t have show NSFW enabled on my account and I was mainly scrolling All(with a heavy amount of comms blocked) so I can’t figure out what’s causing this.
In the meantime, until the cause is identified, I think having a functional cache size limit would prevent the cache from exploding in size.

You should be able to long press on the video to see it.
I’m going to look at some sort of checksum validation in the next release, although I will only know the checksum once the file has been already downloaded so I might need to come up with a different approach. One change I did make for performance reasons is that instead of checking the total file count against the file limit on every download it’s being throttled to every thirty minutes (in theory…).
Wait, it’s back in my cache already? I have never seen this video before. Is there a way to view where its coming from?

I’ll look into adding some association between a post or comment and the file. Right now I’m just iterating over files in a cache directory and showing their sizes.
From printing checksums locally this did lead me to a race condition where we were preloading an image at the same time as displaying it and neither approach saw the other one so multiple files got cached. That’ll be fixed tonight…
Looking into this specific video more it’s from this guy which is on the All front-page. The thumbnail is actually the full MP4. I’ll add some checks to ensure it’s only images being preloaded in v323.
Sadly, I already cleared the cache. Will try it out next time though.
