Bottom of the map cuts off sometimes, is this normal?

So pretty much the entire time I have used Roll20, for multiple years now, there's a bit of a visual glitch that I've always noticed. On maps of a certain size range (not sure the exact size but it seems to be maps close to the size of the window itself?), depending on how much I scroll down, the bottom of the map cuts off. This has always been the case as far as I remember, has happened on every computer I've used, and persists between Chrome and Firefox. One of my friends mentioned they've also encountered this, but only when they're the GM of the game, which now that I think about it might be the case on my end but I don't have friends' games I'm in at the moment that I can test this in. It doesn't really cause a problem for running games or anything, but it is kind of visually annoying and lately I'm using maps of this size a lot more so I'm seeing it a lot more. Has anyone else encountered this or are my friend and I the only ones? <a href="https://gyazo.com/2a97592198c5a43b53eb587a42850fc7" rel="nofollow">https://gyazo.com/2a97592198c5a43b53eb587a42850fc7</a>

It is a known issue. Someone has reported this (and thinks they found the likely cause) here: <a href="https://app.roll20.net/forum/post/8455731/canvas-scrolling-bug-with-likely-cause-in-code" rel="nofollow">https://app.roll20.net/forum/post/8455731/canvas-scrolling-bug-with-likely-cause-in-code</a> and that info has been passed on to the devs. It's not just you, and nothing is being deleted from your map - it's just a display bug.

Huh, interesting to actually see the logic behind what seems to be causing it. Glad to know it's known then, for a while I was wondering if it was just me and a select few people and if I was going nuts since I couldn't find any threads talking about it, haha.
