RStheme: Editor text changes brightness after activating editor window pane.

[ddkddk]

Hi. I use a dark theme that is slightly adjusted from the 'vibrant_ink' theme. Over the past 6 months or so, I started noticing that the text changes brightness when clicking within the text of a script. It is especially noticeable with the comments colour of my theme and for larger scripts where you can scroll down quite a bit. If you want to see what I mean, use the below theme that I use (it is also slightly visible with just the already installed vibrant-ink), type a line of comments, copy the lines below each other (alt+shift+down arrow) for a 100 lines or so, click on the first line, scroll down, click on the last line. The moment you scroll down you should notice a difference in brightness of the text and when you click on the last line the brightness changes again. It's not too much of a bother, just wondering if there is any option to turn it off.
