If you are using RStudio on Linux on a Wayland compositor and you have a HiDPI monitor, you might be wondering why it's all blurry. I have some good news for you. I've been trying to get it to work for a while too and I finally did today.
From terminal, run RStudio using:
`rstudio --disable-gpu --enable-features=UseOzonePlatform --ozone-platform=wayland`
