2 LEDs missing with ledmap.json
What happened?
Without ledmap.json all LEDs (1536 with 384 LEDs on 4 different GPIOs) are working. With ledmap there are 2 LEDs missing
To Reproduce Bug
I use 24 ws2812 8x8 Panels. On 4 GPIOs i connected 6 Panels in dequence. So alltogether there are 24 Panels with 1536 LEDs. Like that:
GPIO16: Panel1-2-3-4-5-6 GPIO17: Panel7-8-9-10-11-12 GPIO18: Panel13-14-15-16-17-18 GPIO19: Panel19-20-21-22-23-24
and each Panel consists of 8x8 LEDs in non-serpentine arrangement.
Since i can't define 24 Panels with the Panel-Setup i tried my luck with ledmap.json:

better to read:
I did it several times and i am pretty sure i did everything right, since "scrolling text" is working well, BUT: The first 2 LEDs of Panel 13/14 are dark an it mostly looks like they are mixed in LEDs 1534 and 1535.
Of course i have no defined skipped LEDs and i also douple-checked the GPIO Definitions - i am quite sure that everything is right, since it works (of course with unreadable scrolling text) when i delet the ledmapping.json . And if i swap GPIO 18 and 19, the problem change to Panel 19-20.
Is that maybe a problem with the ledmapping function?

@DarthWeber I have seen that reported before with large ledmaps , what worked for others and you might want to try is change JSON_BUFFER_SIZE in const.h to 50000 and test again https://github.com/Aircoookie/WLED/blob/main/wled00/const.h
Great, that solves that problem. Thank you!
Just to avoid keeping different versions: Can i use this buffer size for all instances or is there any way to define this in the platformio_override.ini?
I do not think a platformio flag is there at the moment and as far as my limited testing that did not impact the units in a bad way so you could just OTA the same bin to all your other units . If you are having concerns then test with one unit for a day or two
0.15 will implement increase in JSON buffer size (in general for ESP32 and variants) and double that on devices with PSRAM. Until then it may not be safe to increase JSON buffer without thorough testing in various configurations.
Available in 0.15.0 beta 1. There is still a limit on the size of ledmap. It has been increased to support larger LED count though.
