weird html rendering in rmarkdown in latest Rstudio app (still not solved)

Hi, I downloaded the rstudio of latest version, but weird things happened. when I use highcharter or plotly to generate html graph in rmarkdown, it looks dim.

but when I move my cursor to that html graph, it becomes lighter, it's really annoying, does anyone knows the reason?

This is not a bug per se but a disagreement with a design choice. I think a better venue for discussing this, is filing an issue on the GitHub repository for the RStudio IDE

Hi, thanks a lot, I've submitted one in the github. this is the link weird html rendering in rmarkdown in latest Rstudio app (still not solved) · Issue #13524 · rstudio/rstudio · GitHub
