Steps to reproduce:

Right-click on a web page on a Windows 7 machine

Actual results:

A functional context menu appears, but the colors are broken: hover box is black, so the user can't see the text (see attached image; cursor is over the "Refresh Page" button), the hovered button doesn't change color, yet the pictograms or letters on the hovered button become white.

Expected results:

A context menu appears with visible tooltips and distinguishable hovered buttons

The Bugbug bot thinks this bug should belong to the 'Core::Graphics' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Are you able to use mozregression to help us find what change might have caused this?

Also, can you please attach your about:support information?

After the last update the problem disappeared, I couldn't reproduce it even with mozregression. Now the context menu looks ok.
