For certain rgb matrix effects, when all (or most) LED's are blank, random keys will flash a random colour. This seems to (subjectively) be focused on keys in the bottom right quadrant (last 2-3 rows, and coloums to the right of space) but I've seen this behaviour across the entire keyboard. This behaviour seems similar to #23619 though with different triggers, as I see the flashing when no effect occurs, rather than when an effect reaches a particular part of the matrix.
The affected rbg matrix effects include:
breathing (in between "breaths")
band_val (but not band_pinwheel_val or band_spiral_val)
typing_heatmap, but only if I haven't typed in a while, i.e when the "heatmap" dies down. I need to type a few words to get enough "activity" to stop the bug. Typing that sentence for instance was enough.
digital rain, for the first ~5 seconds
solidreactive[simple, wide, multiwide, cross, multicross, nexus, multinexus, splash, multispash, solid_splash, solid_multisplash] all have the bug in between typing, when all keys are blank.O

Additional Context
I have an Anne Pro 2 (C18) flashed with almost the default keymap (see https://github.com/OmegaLambda1998/qmk_firmware/tree/master/keyboards/annepro2/keymaps/OmegaLambda). I then flash AnnePro-Shine to get lighting functionality. I have flagged this issue with the OpenAnnePro team as well.
