svn build rev 11499 (2018-10-07 09:45:50) gcc 5.1.0 Windows/unicode - 64 bit
Settings->Editor->Syntax Highlighting->Matching brace (background color): is getting reset.
You can only notice this when the background is dark.
If you set the matching brace background color to match that of the background, after a while it will get reset to having a white background.
If you change the setting, it seems to be being stored, because if you enter to the syntax highlighting window and save without making changes,
the braces will temporarily take the value you had set to them. My guess is that the value is being reset in memory from somewhere else.
Cheers!
