For the past 2-3 weeks I've had an issue on my Ornata Chroma where the [enter] and ['] buttons have a random lag before then become responsive. It takes anywhere from 3 to 15 clicks before it responds. Afterward, for the next 5-10 minutes it works normally only to revert back to the previous state of being unresponsive. I have not observed this behavior on any other keys. I have been using Synapse 2.0. After a clean re-install, the same behavior reappeared within a few hours. I have no macros and no button mapping for the Ornata. I also attempted to uninstall Synapse 2.0 and use the keyboard without Synapse but I ran into the same behavior within 5 hours. Resets don't clear the behavior. It doesn't "appear" to be a hardware issue, it works normally for 5 minutes after ~10 unresponsive clicks (then reverts back). I also have attached an Orbweaver and an Ouroboros. Those do have button mapping assigned to them. From the steps I have taken and the behavior this looks to me like a firmware issue but Im not sure. Please help!!!!
