Firefox Rendering problems

[trafficonese]

This problem started some weeks ago and it is apparently only with Firefox. I also tested Chrome, IE and Edge and they work fine. So I'm not sure if this is the right place to post it.

In the upper part of the plot, some artefacts show up, which seems to happen with geom_col, geom_point, geom_histogram and maybe more. I just checked those functions.

Shiny-code:

library(shiny)
library(ggplot2)
library(plotly)

dfN <- data.frame(
  time_stamp = seq.Date(as.Date("2018-04-01"), as.Date("2018-07-30"), 1),
  val = runif(121, 100,1000),
  col = "darkgreen", stringsAsFactors = F
)

ui <- fluidPage(
  plotlyOutput("plt")
)

server <- function(input, output, session) {
  output$plt <- renderPlotly({
    key <- highlight_key(dfN)
    p <- ggplot() +
      geom_col(data = key, aes(x = plotly:::to_milliseconds(time_stamp), y = val, fill=I(col)))
      # geom_point(data = key, aes(x = plotly:::to_milliseconds(time_stamp), y = val, fill=I(col)))
      # geom_histogram(data = key, bins = 10, aes(x = plotly:::to_milliseconds(time_stamp), fill=I(col)))

    ggplotly(p, source = "Src") %>%
      highlight(selectize=F, on="plotly_click", off = "plotly_doubleclick", color = "blue") %>%
      layout(dragmode = "select", xaxis = list(tickval = NULL, ticktext = NULL, type = "date"))
  })
}

shinyApp(ui, server)

Looks like this might be due to a bug in FF itself plotly/plotly.js#3393 (comment)

It'd be much appreciated if you could try with FF 66 when it's released and report back on whether it fixes your issue

It seems to be fixed now.
