Are Steve McQueen and John Ridley Feuding?

After John Ridley won the Best Adapted Screenplay Oscar on Sunday night for his work on 12 Years a Slave, 12 Years director Steve McQueen offered a less-than-enthusiastic palm clap for his colleague. And then Ridley refused to thank McQueen during his acceptance speech. What gives?

According to Hollywood reporter/tweeter Nikki Finke, the two men are on unpleasant terms regarding the film's screenplay:

My sources attributing John Ridley-Steve McQueen cold shoulder at Oscars tonight to dispute over screenplay credit.
