Small Stutter in Case RGBs on Linked Mode

Please read these quoted sections before submitting, and remove them (including this one) when you have provided what
is asked, in order to make addressing the issue easier for everyone. Thank you!

Be sure to:

• Check the documentation HERE to answer many questions on firmware capabilities and usage.
• Make sure that your issue has not already been filed HERE.
• Confirm your issue exists on the latest version of the firmware, found
  HERE.

Expected Behavior

The case rgbs in linked mode should be displaying the same custom theme as the top. If you use any of the linked modes, these should display consistently.

Current Behavior

The case rgbs seem to "stutter" randomly at random times. This is only happening in linked mode and not in actual ambient mode. There doesn't seem to be a "regular" interval, its somewhat random.

Context

Please provide all relevant information about your setup. This is important in case the issue is not reproducible
except under certain conditions. Important elements include:

• 0.7.11
• Haute42COSMOXMultra
• COSMOX M-Ultra
• :)

If your issue is with the web configurator, also include:

• Operating System
• Browser

Steps to Reproduce

Please provide detailed steps for reproducing the issue.

1. Set the M Ultra ( or M Lite) to ambient case linked mode
2. Setup a custom theme in the web config
3. Change the button colors over to custom theme and wait
4. Watch that the LEDs flicker randomly every like 45-90 seconds

Screenshots & Files

Please include any relevant screenshots, photos/recordings, or files here.

No source file, test, or entry point is named. First reproduce the random flicker on firmware 0.7.11 using ambient case linked mode with a custom theme on the M Ultra or M Lite, then trace the linked-mode RGB handling. Done means linked case RGBs consistently match the top theme without periodic stutter.
