title="REOPENED - Rx480 doesn't output properly onto z27q at 5120x2880"
href="show_bug.cgi?id=99801">bug 99801</a> is basically what I'm seeing also on i965. Although that's
on HP Z27q however the corruption/flicker seems to match. You may try to
acquire this one for testing if the Dell UP2715K is not available anymore.
So this bugreport has been open for almost two years now with little to no
improvement... Who should I bribe to make this issue fixed? :-) If there's
anything else needed from the reporter side, please let us know.</pre>
