What happened?

with a fresh/new install of WLED 0.14.0 the TM1814 protocol appears to not work any longer but it did with 0.13.x
In a TM1814 LED strip, all LEDs turn red and a few may flicker when using no effects regardless of what color is set in WLED.

Current work around is to uncheck “Use global LED buffer”. Once this is unchecked, the TM1814 LEDs appear to work as expected.
Not sure what this setting does.

To Reproduce Bug

using firmware 0.14.0, and TM1814 LEDs, set the LED output to TM1814 and make sure "use global LED buffer" is checked (appears to default to checked). and use solid colors (effects set to none).

my setup: 12v TM1814 puck LEDs with 20 addressable pixels and using a digiquad ESP32-ethernet bench testing.

Expected Behavior

expected the TM1814 LEDs to be controllable with WLED when LEDs configured to the TM1814 protocol.

Install Method

Binary from WLED.me

What version of WLED?

WLED v0.14.0 (build 2310130)

Which microcontroller/board are you seeing the problem on?

ESP32

Relevant log/trace output

No response

Anything else?

initial discussion in the forum: https://wled.discourse.group/t/wled-v63-controller-tm1814/9649/10

I realized after more testing that if I revert back to 0.13.x TM1814 would work, but going back to 0.14.0 did not work. from other discussions about TM1814 being sensitive to other processes going on, i started looking for other settings to change and disable. So I happened to try unchecking use global led buffer and after clicked "save" the output was working again. I'm not sure what this setting does and if it was introduced in 0.14.0 or not, but it appears to be checked by default and currently causing the issue.
