Server freezes/resets when disabling FastLED interrupts

[bwarman]

I was having blinking/glitchy LEDs on my strand due to interrupts on my Wemos D1 Mini. Previous issues solved this with

#define FASTLED_ALLOW_INTERRUPTS 0

Now the blinking is gone but the server freezes or resets at random intervals. I assume it has to do with watchdog resets but I've been unable to completely diagnose it.

Try WiFi.setSleepMode(WIFI_NONE_SLEEP); at the beginning of setup.

That causes the server to freeze completely and not even serve a page. The serial monitor shows the connection and the browser never loads the page. I've diagnosed it as watchdog timer resets. This is the serial monitor output when it freezes:

ets Jan  8 2013,rst cause:4, boot mode:(3,6)

wdt reset
load 0x4010f000, len 1384, room 16 
tail 8
chksum 0x2d
csum 0x2d
v0c897c37
~ld

It takes a few manual button resets to get the server responding again. That probably has something to do with the dropped connection and not necessarily a bug, so to speak. Seems to be a common ESP8266 problem when disabling interrupts. Any solution?

Let's try this again. Replying through email fudged the post pretty badly.

Remove #define FASTLED_ALLOW_INTERRUPTS 0
and replace it with
#define FASTLED_INTERRUPT_RETRY_COUNT 0

Keep this at the beginning of the setup function though:
WiFi.setSleepMode(WIFI_NONE_SLEEP);

Confirmed fix on my end. Adding:
#define FASTLED_INTERRUPT_RETRY_COUNT 0
before
#include <FastLED.h>
and adding:
WiFi.setSleepMode(WIFI_NONE_SLEEP);
in setup() fixed my issue.
No glitching pixels and no watchdog resets. Closing the issue.
