Image files go blank upon closing RStudio

[michaellevy]

A few times (out of 20+ sessions using the package), I've had png files created with agg_png go empty after closing the RStudio session in which they were created. The files still exist in their created resolution, but they go from being full of content to being blank white. The latest time, the png files were open when I closed RStudio -- I watched their content disappear -- but I don't know if that has always been true. I'm sorry I can't provide a better reprex for this; the code I always use to create the files is bellow and session info below that; let me know if anything else would be helpful.

agg_png("file.png", width = 1500, height = 1500)
ggplot...
invisible(dev.off())
system("open file.png")
