Intel Graphics Performance Regression on 5.8

Upgrading from 5.7-12 to 5.8 drastically reduces my performance on an Intel® HD Graphics 4600 when it comes to not-so-demanding tasks like scrolling simple web pages or various GNOME Shell animations. High-demanding tasks such as 3D benchmarks don't seem to be affected much.
Another thing that I've noticed is that leaving some moderately demanding task open (such as glmark2) greatly increases performance in the mentioned areas. So might have something to do with frequency scaling? (A simple frequency comparison of the same task is shown below)

Left one is 5.7 and the right one 5.8.
Any ideas about this issue? Where should I file a bug report if that's the case?
Thank you.

I can't really help, but maybe it's related to this? They should be "small " though according to the article.
