The problem is as follows. I purchased a RAZER BLACKWIDOW V3 MINI HYPERSPEED, and when connected via a cord, everything works perfectly and without complaint. However, in the case of wireless connection, there are problems with the backlight, namely, the lighting macro may lag or freeze. Also, after the backlight goes into sleep mode, when you return from it, the backlight freezes in a static format. You have to turn the keyboard off and on again to make it work. I reinstalled Synapse 4, but it didn't help.
