I have a Windows 10 laptop and a larger second screen I extend to where I use RStudio. All the text in RStudio is clear except for the Editor window, which is sometimes blurry. But only sometimes. It starts out clear. f I run a script, sometimes it goes blurry, sometimes not. If I just scroll all the way down to the bottom of the window, as soon as I hit the end, all the Editor text goes blurry - this always happens. The only way to clear it is to scroll back up to the top - which always works.
This feels like a bug, but does anyone have any ideas? I don't have issues with blurry text in any other window of RStudio, and the behavior is the same whether I am working with a Markdown script or an ordinary .R script.
