First, I'd like to say a big thank you for making this. Once I got the hang of this app many months ago I haven't been able to stop using it to make maps for my games. Even when modules provide maps, I sometimes prefer to make my own versions so as to avoid weird grids (1 square = 10 ft is bananas in roll20).
Now on to the main question/request I have: when exporting maps that use any lighting, there is always a series of visual artifacts creating a noticeable "phantom grid". The reason I say it's phantom is because the lines are blurry and don't align to the grid lines created by the software. In most cases, it's also more noticeable than the grid lines themselves. Below is just a recent example (cropped for size) from many maps I have created. This isn't stopping me from using it... just wondering if this is in the works to remove and... to some extent if there is anything else I can do to help.
