WLED_0.11.1_ESP32.bin not all 100 leds used and some blink

Issues
1

Hi,

I’m new to WLED, and need a hint what’s going on with my setup.

I have an MH ET ESP32 mini board and a 100 LED WS2812b strip with 5V 4A power supply.
The setup works fine, including full white (ok, with some darker leds at the end) with test programs like Adafruit neopixel strandtest.

When flashing WLED_0.11.1_ESP32.bin not all LEDS are operated and some blink even on SOLID effect. It is not only the leds. The peek function of the webpage also displays this “effect”.
If I select color 2, then the dark leds use this color. But the blinking of some leds remains.

User error or bug?

Tested down to version 10 - all with the same problem.
Erased flash and started over. Now it is gone. All fine now.

What flasher are you using as some are known not to fully erase the controllers memory? People then often report glitches after programming.

At first I did not erase flash. It was a factory fresh chip with a blink sketch running.
Then I erased the flash with esptool.py as provided by opensuse 15.2 with the command from the wiki.
