How to get rid of macOS dGPU switching?

I'm using Firefox 61.0.1 (older versions also affected for a couple of months now) on a high end specced 2017 MacBookPro 15" with Radeon Pro 560 running on macOS 10.12.6. Although I turned off hardware acceleration the browser constantly switches between iGPU und dGPU when rendering a page (including the obligatory page flicker while that happens). This makes Firefox completely unusable for me and no other browser I've tested (Opera, Safari, Chrome) shows the same behaviour, in Opera I can even leave on the hardware acceleration and just disable "Allow use of computer's dedicated GPU".

That sounds more like a Mac driver issue and not related to FF Browser. Did you look at Apple forums before here?

I don't see how that would be a driver issue if it works for all relevant applications except for Firefox. Just for kicks I checked the Apple Support Community site but there doesn't seem to be anything of relevance there.
