Caption text background issue with aeroglass

[innuendo]

Is there anybody who knows how to get rid of caption solid text background ?
Had an issue when setting a specific color ( pink in screenshot ) I get all my caption text with such background color and unreadable then
I know Aeroglass is messing that since when uninstalled all is fine with custom themes. I remembered have seing such issue in the past but can't retrieve the topic here or on aeroglass forums bah do not get old :/

Is there any registry key where to override this or something in themes to edit to avoid that ?
Thanks for any help , get annoying :/
