I’m having an issue with my dropdown selections being hidden. However, this is not a problem on Mac OS X
Summary
For example, I would click the drop down and all I see is the white box.
The reason for this is the background color is #2C2F33 (Grey-black) and both Placeholder and Text Color are #FFFFFF (White) Because, when you click the dropdown, the selections background is white, it makes the text unreadable unless you hover over it, making the background blue.
