I want to use a dark UI theme and a light editor theme. I've been doing this without issue for the last 2 years, but since the 2018.3 update I've been having trouble with it.
What happens is every time I restart PhpStorm, my color scheme is automatically changed to Darcula. I see the light theme there for a moment before it changes, so it seems to be happening when the app starts. Then I have to manually change it back. It's driving me up the wall.
If I use a dark editor theme, it is retained on restart. Also if I set the UI to have a light theme, I can use a light or dark editor theme and it is retained. It's only the combination of dark UI / light editor that PhpStorm seems to have a problem with.
