[Bug] Degraded performance when rendering large images in the bookmarkgrid

[Antebios]

I have over 15k bookmarks that it took a long while to import. After it finally imported the UI performance was excruciatingly slow. I waited a few days later to try to use it again since it might have a background job, but it was still slow. I even restarted the service, but still slow. I have given up using it.
