I can more or less confirm.
The problem is with syntax-highlighting.
If you type the first bracket, there's no matching bracket that closes it.
The caret is just behind the bracket and it is highlighted as "No matching brace highlight".
That defaults to white on red.
Because of the option "Highlight line under caret" the background does not become red, but light-yellow.
And white on light-yellow is really hard to see, but if you really try, you can see the bracket.
I'm not sure if it is a bug, but I think the highlighted brackets colour-setting should overwrite the highlighted lines colour-setting, and not vice versa.
To get rid of the problem you can change the colour-setting in a way, that this problem does not appear.
