Even if the issue happens randomly, it would still be helpful for us to see a small, self-contained example Shiny app that the problems occurs in so we know where to look.

6 years ago @wiwie It shouldn't attempt to render the plot if it isn't visible, are you using outputOptions to stop suppressing output?
@ChristianGeng I think that's just what happens when the div is too small for quartz to try drawing a plot, can you make it bigger?

6 years ago Yes that is true, I was indeed using it. Removing it fixed it for me.

6 years ago Thanks very much for the help! It size of div hint helped me to figure it out: I replaced the line "uiOutput("distPlot")" with "plotOutput("distPlot")" in above example. That fixed it for me.

4 years ago This might help some people.
I had a similar issue when trying to style my app using divs and css.
The workaround or fix was to explicitly set the width of the div (fixed pixels or %) so that (I'm guessing here) the rendering process has a predefined width/height to work with.
Note: my plot outputs only have height defined server side.

Hi, I have an issue which seems to occur randomly since upgrade from 1.0.5 to 1.1.0. I tried to isolate it without success. It seems to be linked to my slow server running on Ubuntu 16.04 with shiny server, as locally, I don't get any error. I don't have Cairo installed (therefore pngfun is grDevice::png)
My renderPlot function does not contain any other argument than
expr
