I stopped using RGB Fusion because it was hitting my CPU at 9-10% (a known issue) plus caused other problems with my NLE & DAW software. More specifically, it was tied to the "App Center" used to install & run Fusion... Gigabyte may have updated it (dunno) try installing the latest version and see if it fixes it.
Alright, I'll try updating and see if it works thanks.
Worse case, you can always set the Mobo RGB lighting in the Bios instead of using Fusion. It's not as detailed as fusion and lacks quiet a few options, but at least you can set color and a few cycle options.
