Map Grid Extending Beyond Map Bounds at Certain Zoom Levels

Good morning.  I have had this niggling problem since I began using Roll20.  At certain Zoom Levels the window shows the map grid extending beyond the edges of the map bounds.  This happens regardless of the dimensions or proportions of the map.  It fills in the extra grid with the background color of the map.  Example below (First is at one zoom level, second is same map zoomed out one level, third zoomed out one level more): My Chrome Version information below: Google Chrome 70.0.3538.77 (Official Build) (64-bit) (cohort: Stable) Revision 0f6ce0b0cd63a12cb4eccea3637b1bc9a29148d9-refs/branch-heads/3538@{#1039} OS Windows JavaScript V8 7.0.276.32 Flash 31.0.0.122 C:\WINDOWS\system32\Macromed\Flash\pepflashplayer64_31_0_0_122.dll User Agent Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36 Command Line "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --flag-switches-begin --ignore-gpu-blacklist --flag-switches-end Executable Path C:\Program Files (x86)\Google\Chrome\Application\chrome.exe

This is a behavior related to the implementation of Canvas, so far as I have had is explained to me. Try putting in a buffer of several grid units around the edges of the map. If you don't want them to be obvious to players, you can color the background a similar color or cover them with regular fog of war (which is also handy for keeping reinforcements or hidden tokens in).

Interesting!  Does regular Fog of war play well with dynamic lighting/adv fog of war?

Regular fog of war adds practically no measurable overhead to performance so far as I understand. It's basically a dumb opaque layer on top of everything. Here are some uses for that space: Quick and Dirty Invisible Token Tracking Using Basic Fog of War Quick and Dirty Slide Show and Image Display
