--- Comment #1 from Bernhard Kölbl  ---
The problem with this test is, that it seems to be suffering from an AMD driver
bug. When you look at the generated image it's really clear that it's garbage
output. The only real way to fix this test would be to check for GPU vendor and
skip the tests accordingly, not sure if that's a good solution though?

The goal should be to understand why it's different on AMD, not simply
skipping.
