What's the problem? Describe what went wrong.

On ubuntu 15.10, with radeonsi driver: random white lines in certain places (episode 1.2 for example).
When I put the game on pause, these lines generated randomly (some appear and some disappear).
Could be in scenes with water drops, but not sure.
I tried to change the resolution, graphics settings in Dolphin: no change.
In windows7: the rendering is ok.
I can't say if it's related to dolphin or to the radeonsi driver.

What steps will reproduce the problem?

Launch DK game. Go to stage 1.2 (jungle)
