Same problem here hope they fix it as soon as possible.
We are making a small app for our forum mates in http://aaspot.net but it just doesn't work.
What we are planning to do is to add a message like your card is not fully supported or your card is not supported for this mode or similar.
It looks there is no other solution. Or show a warning to all that some AMD cards are not supported.
Edit: (17.12.2014)
It's been a long time, please inform me if someone found a solution our customers keeps complaining about this problem.
