When plotting a Gviz DataTrack I noticed a grey dot appearing in the center of the plot.

library(Gviz)

set.seed(13)
df <- data.frame(chr = rep("chrI", 30), start = 1:30, end = 1:30, score = rnorm(n = 30, mean = 10, sd = 2))
data.track <- DataTrack(makeGRangesFromDataFrame(df = df, keep.extra.columns = TRUE), genome = "sacCer3", type = "h", name = "x")

plotTracks(trackList = list(data.track), chromosome = "chrI", from = 1, to = 30)

enter image description here

Is there a way to avoid this?

Dear Robert,

Thanks for pointing that out. It is actually result of the check, if device supports transparency. Currently I do not have an idea how to check it in a less disturbing way. However I moved that point to the bottom-left corner where it should be less visible. I committed the change to GitHub repository and will push it into Bioc release and development next week.

Best Robert
