backslash, [, Left Alt stuck red on static lighting- These 3 keys always show red. During fast color cycle effects they display correctly. At boot before SignalRGB loads they also show the correct color. Jiggling the Forced color wheel near the target color temporarily snaps them to the right color, but they revert to red after restarting SignalRGB. Seems like the initial static color packet is being dropped for these specific keys and a second update is needed to correct them.
This looks like a K95 firmware quirk. Those 3 keys default to red on startup, static color’s first update seems to get dropped, but animated effects keep re-sending it so they’re fine.
You can use an animated effect, or nudge the Forced Color wheel then back after loading (once per session).
Could you send us a bug report through the bug icon in the app’s upper right panel? That’ll help us investigate further.
