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)
Which versions of Dolphin did you test on? Does using an older version of Dolphin solve your issue? If yes, which versions of Dolphin used to work?
dolphin-emu (from ppa):
4.0+git+r92~13~ubuntu15.10.1
radeonsi (from padoka ppa):
1:7.6.99+git1512301505.c7cf004~padoka0
What are your PC specifications? (CPU, GPU, Operating System, more)
i7, 4770K. Radeon HD7850 on radeonsi open source driver. Kubuntu 15.10 update with latest radeonsi drivers (from padoka ppa;
1:7.6.99+git1512301505.c7cf004~padoka0).
Is there any other relevant information? (e.g. logs, screenshots,
configuration files)

I think that's the same bug we've been randomly seeing on FifoCI. So we're already aware of it and it's almost certainly a radeonsi bug (an apitrace of the rendering doesn't have the lines when rendered on i965).

Apitrace: http://delroth.net/radeon-unpredictable.trace
I'll keep this open to track a fix on the Mesa side.

Also, this bug was marked as Fixed after the blacklisting.
In this kind of case, shouldn't an other status be used while waiting for a proper fix in the drivers, to be sure not to let a blacklisting in place longer than needed?
