I noticed that for some reason I had about 6 versions of Roblox installed on my device, so I went ahead and reinstalled it. I opened Roblox Studio, changed the UI_Theme to dark, and then proceeded to open up a script to continue with development.
It was at that moment I was greeted with a pure white display which has now permanently damaged my eyes after hours of developing in the dark.
In all seriousness, the script editor doesn't seem to update like it used to to match your UI theme, i.e dark.
