So, i've had this keyboard for 3-4 months. and there was no problem. however, recently the rgb lighting and profiles started to get laggy when i'm not using my computer. the rgb effect stutters, especially the rainbow effect. it gets back to normal when i move my mouse or press a key on the keyboard. And the second problem that i have, is some of the rgb lights either turns off by it's own, or changes to another colour. this happens to 1/2 keys when i left my computer on for 15-30 minutes. i had to change profiles to get the rgb lights working again. Is there a way to fix this?
