Comment 35 for bug 1837170

Just tested your ppa with mesa 19.2.1-1ubuntu1~18.04.1~ppa2, thank you

Since mesa 19.0.8-0ubuntu0~18.04.2 the image produced by Ubuntu with all media players and browsers is very dark, like the contrast and black levels were adjusted at a very low value. It became worse than before, including yours from x-swat.

I noticed this contrast darkness increases progressively with each kernel upgrade, starting from 5.0.0-27 to 5.0.0-32; I'm using 4.18.0-15 to minimize this effect.

I tested a Radeon R7 250 card, compatible with A-10 series APUs, and got the exact same bug. So the problem is not only with AMD APUs, but with the entire AMD R7 Graphics series, if not all AMD stack.

You guys need to test more AMD hardware.
