library(ggvis)

ui <- fluidPage(
  sidebarPanel(
    sliderInput("size", "Area", 10, 1000, value = 10)
  ),
  mainPanel(
    uiOutput("ggvis_ui"),
    ggvisOutput("ggvis")
  )
)

server <- function(input, output) {
  input_size <- reactive(input$size)
  
  mtcars %>% 
    ggvis(~disp, ~mpg, size := input_size) %>%
    layer_points() %>%
    bind_shiny("ggvis", "ggvis_ui")
}

shinyApp(ui = ui, server = server)

Describe the problem in detail

Hello,

My ggvis plot isn't displaying properly using Shiny version 1.9.1. It appears greyed out. When I reverted to version 1.8.1, the plot displays correctly. I realize ggvis is dormant and hasn't been updated in a long time but I still use it for some tools I created years ago.

Greyed out plot using Shiny 1.9.1:

Correctly displayed plot using Shiny version 1.8.1:

Thank you

Thanks for the report @richarddirocco. There were some changes in 1.9 that improved our consistency with how we report output state. It seems, however, that ggvis gets stuck in a recalculating state. @cpsievert might have some insight about the bug.

As an interim solution, you could disable the fading during recalculation for ggvis outputs with this CSS rule:

.ggvis-output.recalculating {
  --shiny-fade-opacity: 1;
}

I'm also getting this issue with mapdeck, and setting

.mapdeckmap.recalculating {
  --shiny-fade-opacity: 1;
}

is working as an interim solution
