Description:
When I take the mouse over UI elements, their font gets white and becomes unreadable. For example, the fonts drop down list in all the products (calc, writer, present), grid labels of selected cell (A,B,C,.../1,2,3,...). Setting
I tried resetting user profile. Installing 6.3 and 6.4 releases. I also tried enabling and disable Open GL and CL, but the problem is still there. The problem only appears in the dark theme of OS X.

Steps to Reproduce:
1. Enable dark theme on OS X
2. Open Calc 
3. Selected UI elements become unreadable

Actual Results:
UI elements become unreadable

Expected Results:
UI elements should be readable


Reproducible: Always


User Profile Reset: Yes
