As far as I can see, the texture loaded from a bundlefile in BundleFileImageSource will never be disposed of when unpinned. Could it be a possibility for you to add a flag to dispose the texture when unpinned?
This has been fixed, but due to a small mixup hasn’t made it into the release yet. Sorry about that. We’re hoping it will be in the next release.
Ah so this will actually dispose it as well as not preloading it, awesome
