Multi Display Adapter Support

[dannyfritz]

I get this weird behavior where on one of my monitor Milton doesn't appear to do anything at all. But when I drag it over to my other monitor, it shows what I was intending to be doing. Then when I drag it back, it again looks like it doesn't draw anything at all. And dragging it back again, I see what I was trying to draw.

Hard to explain, so here is a recording of it.

One thing important to note is that the 2 monitors are running over 2 different display adapters, one is DisplayLink and the other is an Intel HD 620. So Milton is choosing the Intel HD 620 and not working on the other adapter.
