I guess not! There was another thread that had recommended this baudrate for SK6812 strips which I found while diagnosing a different issue.
I'm now down to 4000000 and haven't seen a flicker in a while.

I think this might be a baudrate problem! I played around with a few different values and the flickering is now gone when I load the web UI. I currently have it set to 4500000, but I'm still seeing the occasional flicker while watching so I think I may need to tweak this further.

I'm curious if anyone else has experienced a fairly dramatic LED flashing when loading Hyperion's web UI?
This happens 100% of the time I load the web interface. I also get a similar flicker randomly while watching content (1 quick off/on every couple of minutes).
I'm about 80% sure this is to a system resource issue. I can also reliably create a similar flicker by SSH'ing into the Pi and running commands (for example, `top`).
What's interesting is that when I look at the system resource usage on the Pi (using `top`), I never see the CPU utilization exceed 20%, and memory utilization never exceeds 10%. This is true even when performing actions that cause the flicker (e.g. loading the web UI).
My setup:
- Raspberry Pi 3 Model B Rev 1.2
- LEDs: SK6812 (172 total LEDs) on pin 19
- 3.3v to 5v level shifter: no
- Controller type: sk68712spi
- Baudrate: 5900000
- Hyperion version: 2.0.16
Any ideas?
