When zoomed out too far the pan refuses to pan and is justified on the left side

1539320515
Issue: When the screen is zoomed out the map/screen refuses to pan left and right. One of my friends called this bug a 'dealbreaker' before our first campaign.  Description: This is my first campaign on here; I was testing a map with a friend in preparation for tomorrow. Playing the first encounter map in Mines of Phandelver (which is a really small area), if you zoom out far enough then you cannot pan the map left or right. With this, and the video feeds it can end up blocking a huge chunk of the map. Steps: 1. Zoom the map out and try to pan left or right. 2. Add 2-4 video feeds and this leads to a huge chunk of the map being blocked. 3. If you zoom in then you can pan the map left and right, but zoom out again and at a relatively close view the left-right pan  Fix: If you can pan the map even if fully zoomed out, it would be a huge improvement. Especially to those large parties that want to have the video feeds remain as large as possible. 
This is an issue for me too.  Can I "second" this?

Hang on, I have alerted the devs on this. I'm not sure if this is a bug or not, but I believe it is a known behavior of the canvas.

No, but you can "Ten-thousandth" this. We've been asking for this to be fixed practically from day 1. They're working on it. edit: Really keithcurtis? I don't have time now, but I can show you dozens of posts about this later if you wish.

Best way I know to work-around this issue is, make your page size much larger. Have large margins in your Page, around your live map area, and perhaps blacken those margin areas with dark background color, or solid Fog of War.

I have added the information here to the existing ticket on this issue and alerted the devs. In the meantime, a few workarounds that might alleviate the issue for you when trying to span entire maps: WebRTC screens can be moved around at will (see: Movable avatar/video screens option in the game settings) WebRTC screens can also be resized or hidden as well (see:  Player video/avatar size option in the game settings)

Gold brings up a good tip. I've probably not noticed this much because I habitually pad the margins of my maps. There are some useful techniques that can be employed with a good margin of Fog of War. Besides the linked trick, it can be used to hold reinforcements without resorting to a trip to the GM layer, or to hold multiple copies of an NPC who might be encountered at multiple points on the map (Igor knows all the castle's secret passages.)

And the oldest ones I could find: https://app.roll20.net/forum/post/1845/bug-report-new-canvas-covers-scroll-bar https://app.roll20.net/forum/post/2049/scrolling-is-wonky https://app.roll20.net/forum/post/1890/map-not-resizing-correctly From the last of those: Riley D                           August 4,2012 There's still a small error if your screen is just barely smaller than the size of the page where it will "jump" a little when you scroll and show you about 10% more of the canvas than it should, but overall it's much better. I'll try and get that last 10% fixed as well. So yeah, they're working on it.
