I don't think the retina display has anything to do with it. Up until the most recent release of jumpgate, when I changed color on the grid (or made other graphic changes such as lighting) the changes took effect immediately. Now, they don't. Other people reported this, I believe, so I don't think it's my display. The bleed happened when I loaded that graphic (I'm aware of the grid issue) but did not happen when I loaded the next two. Like I said, some of these issues are intermittent. Some graphics force a resize of the page, others don't. I don't know why... the images are generally larger than the page so there should be a resize. keithcurtis said: Here is what I get when I upload that graphic directly to the map layer and choose to resize. The page fits correctly, but of course the grids don't match (2048 does not divide by 70 evenly, and the system has to assume a pixels per cell value.) But I don't show that bleed you are seeing. I have tested on Mac and Chromebook, both on relatively recent versions of Chrome. I am also not experiencing a reload when changing a value like grid color. I don't know if your Retina display has anything to do with the experiences you've been having, but can't test for that. Does anyone using Roll20 on a Retina display have the ability to run a test?
