Flicker on LEDs

[FranzKropp]

Hi,
I have the opotunity to set some LEDs on a strip to a fixed color, different from the rest of the strip. 2 Blue one for example while the rest shows a solid red. On the blue LEDs I have a bad flicker all the time. The red LEDs also hav a flicker, but not so obvius. You has to look twice to see it.

A strange thing is that this flicker not showing up if I attache a 8*8 LED Array.

Any hind what's wrong??

End of the Loop Sektion:

leds[1] = CRGB (0, 0, 200);
leds[4] = CRGB (0, 0, 200);

FastLED.show();

// insert a delay to keep the framerate modest
FastLED.delay(1000 / FRAMES_PER_SECOND);

I figured out that the Problem occours only on an older WS2812 Strip. This Strip works fine for several Years with the Adafruit_NeoPixel Library.

Adafruit_NeoPixel(LEDMax, PIN, NEO_GRB + NEO_KHZ800)

Now:
#define LED_TYPE WS2812
#define COLOR_ORDER GRB
FastLED.addLeds<LED_TYPE, DATA_PIN, COLOR_ORDER>(leds, LEDMax); // for WS2812 (Neopixel)

Hi @FranzKropp I'm having the same issue with my strip. How did you fix the problem?
