Interesting... here I thought this was a long term issue, and due to my USB-link speed or just too much in my project.
I have three sliders; Red, Green & Blue for manual colour adjustment of an RGB LED... They also change positions according to the values of a ZeRGBa widget.
All works just fine until I set the ZeRGBa to White (255, 255, 255)... each of the three sliders show the 255 as the value but all jump to the bottom, as if they were set to 0. This will also happen to individual sliders as well if value 255 is sent from sketch.
Doesn't matter the Android version. App 2.12.0. Library 0.4.6. Server 0.23.2.
