Not sure if this is a Lolisnatcher or a Hydrus problem but the thumbnails of Hydrus are very low quality compared to all other boorus. I tried to edit the preview/gallery quality settings and some other settings but but that didn't solve it.
My bad. I solved it by editing the thumbnail settings of Hydrus, changed the schaling to 200-250 and deleted the cache of Lolisnatcher. Thumbnails are high quality now.
