Hi,
I've got a Razer Blade Pro 17 rz09-03146N92 and I have been very pleased with the device.
I have set the built-in keyboard to a cyan (light blue) color. But a couple of weeks ago the key R started to change its color to a more yellow color. And now also key F4, 4, C and alt have lost their blue color.
I have updated all drivers for OS (Windows 11) and for the HW. I have reset the backlight color within Razer Synaps but the problem remains. I think this is a HW issue with the keyboard leds.
Looking through the forum there is two more that have encountered this issue:
