Hi Nyall, good afternoon,
how the fix is supposed to work? I created a 99 color random color ramp, and by default it looks much better than before, but when applied it is not random at all, see attached image. Thanks!

Apparently the ramp is created well, but is not applied, and the resulting vector or raster is blank.

Do you have a image. I don't have any issues with colour ramps here.

Apparently it is misclassified, see attached.

confirmed, but it works if you use mode "equal interval".
it seems to affect only the random color ramps, other manually created ramps seems not affected.

Hi Nyall,
I just tested master and things seems better but not as good with the old "random" symbology we had in the old symbology engine. See the attached images.
At this point I don't think that makes a lot of sense re-opening this ticket, what I suggest is to open a feature request to add a new renderer ("random") eventually using ideas from the old symbology engine or plugins like http://plugins.qgis.org/plugins/mapcoloring/
