Ugly looks in dark GTK themes.

[dzhoz0]

I am new, I am here.
I am running Code::Blocks on Arch Linux, I use window manager i3-gaps. I configured GTK applications to use the Gruvbox theme I downloaded it from the internet.
The issue is, if I run Code::Blocks with Gruvbox or dark themes the menu bar will look ugly and sometimes unreadable. Running Code::Blocks with Adwaita theme by setting the environment variable GTK_THEME to Adwaita will get Code::Blocks to run with light theme, and the menu bar will look better and readable.
I know that Code::Blocks uses wxWidgets and follow system-wide theme via wxGTK.

The first and second screenshot represents Code::Blocks is run with dark theme and light theme respectively.

Thanks.

That is not the menu bar but notebook tabs. You can play with the styles in Settings -> Environment -> Notebooks appearance and see if one of them fit your needs.

Thanks, I chose Simple tabs style and it looks better now.
