Weird behaviour with RGB

Hi everyone, i have Manjaro 18.0.4, with kernel 5.2. I have a Redragon K552 RGB keyboard, and i noticed that when i type on Whatsapp Web using a certain RGB mode (that flashes faster as i type faster), load goes up to 100%, making my fans ramp up too. This keyboard does not have an RGB software. It is the first time i’ve seen this happen.
