[Bug Report] Issues with Color Wave (still)


Recommended Posts

System Setup:

* Corsair Commander Pro

* 6 x 120HD RGB fans

* Corsair H100i v2

* iCue version 3.5.111


Actions to replicate:

1. Launch iCue

2. Click on Lighting Channel 1

3. Add a new lighting layer

4. Select "Color Wave" and set to alternating between two colours

5. Add a new lighting layer

6. Select "Color Wave" and invert alternating colour selection



The two layers cycle through without issue like so: https://i.imgur.com/luhLSZJ.mp4




The effect looks ok only after creating the layers. After a reboot or even after a restart of the Corsair Service they look... weird like so: https://i.imgur.com/sdFIHv8.mp4


Ps: Is there an official way of reporting bugs for iCue? Or is the forums it? I've tried using the support ticket system but they seem to just want to RMA my Commander Pro.

That’s not a bug. You are stacking two identical predefined effects. You can’t expect the underlying layer to intelligently detect the tiny dark gaps in the wave and then insert itself. When you manually initiate the pattern, the timing is slightly offset (the difference in time when you applied each effect). When you reboot or restart the program, the clocks synchronize and the top wave covers the bottom, as if there was only one wave.


You could try running different cycle speeds, but the effect would be random. What you really want to do is put a solid color underneath. The easy way is a third color overlapped by the color wave. That is not exactly the same, but a whole lot easier than trying to match a color shift underneath. I am not sure the timing will be quite right since Color Wave is now a “swirl” effect in iCUE. An alternative approach might be to abandon the color wave and set your LEDs individually with a 2 color shift. Set the top half of LEDs on the HD fans to Color 1-2. Then set the bottom half to Color 2-1. You can complicate it further by with more colors and more subdivisions.


Using a combination of manual gradients/waves with long tails, you might be able to come close to your original intention, but figuring out the timing to prevent dark gaps can be very elusive.

It doesn't show up quite as well on the video but both layers are inverts of each other, so one goes Blue > Orange and the other goes Orange > Blue. What happens on reboot is that it only shows one layer, except the first and last LEDs are white instead. That looks like a bug to me. I mean try it on your setup and let me know if you can replicate it.

[Revised] It’s possible you get a white edge as the colors and on/off state blur at edges of the wave. However, the colors and effects are not additive, but top down dominant. If you put a green solid on top of a yellow solid, you don’t get blue. You get a green solid. Solid effects with “no holes” will be completely dominant. Put Spiral Rainbow on top of 30 other effects and all you will see is spiral rainbow. On wave and some other spiral patterns you do have gaps where the leds are not active. Underlying effects can peek through. However, you are layering indentical shape patterns with the same timing. It’s like putting a square over another square. You can “de-sync” the pattern by toggling one wave or the other off and then back on to deliberately stagger the pattern timing. That will let the underlying wave peek through at times, but putting two identical timed waves on top of each other isn’t supposed to work.


I am assuming you want to make a 2 color dynamic pattern with no dark gaps. Keyboard or fans, syncing up waves is tedious. You might find it easier to try one of the methods above.

Well I actually like the way this "new" colour wave looks, especially with the offset starts. It was just weird to me that even if one wave overlaps the other on reboot then I'd expect it to show just the one colour and not have the first and last LED go white.

The "white" aspect is the transition from blue to orange across the color wheel. When you run a single instance of the wave, the LEDs power on for color 1, off, back on for color 2. However, with the two waves overlapped, the LEDs at times must transition from orange to blue or vice versa. Those two colors are on opposite sides of the color wheel and you will cross a "white zone" if you were to draw a line between the points. The easiest way to see that is to toggle your waves off for a minute and add a new manual gradient (or color shift). Add a blue dot and an orange dot to the opposite end. As the fan transitions from one to the other, you will see the clear white shift. You can avoid the white shift by using adjacent or non-polar opposite colors. Red-Yellow or Red-Green won't shift through the white zone. Red-turquoise will. This color shift rule applies to all the devices, although easiest to run into on the mice. Running your overlapped waves with red-blue and blue-red does not produce the white effect since they are not direct contrasts.
