my micro-sized page is kind of inconvenient
(applies to small avatars under 128px tall as well)

Was that your intention to have your cute image stretched out like that? LMAO

At least on the new.ppy.sh page, the design isn't limited by any scrollbar.

I don't think our devs will fix this because our new forum design is almost there, which will replace the current forum.
But just in case, I'll confirm this as low priority.
