Every input lights up the actuation led indicator (above arrow keys) and there is no way to disable it. The constant flashing into my eyes is unbearable, deal breaker for me.
I also have a regular Huntsman v3 pro TKL(not 8K) that does not do this, and that is fine.
Sounds hard to believe a 260€ fully customizable keyboard does not have such basic QOL feature.
Reviews I have seen did not mention this.
