2-3s initial delay after waking up from idle on m5stack Core2 v1

[Girgitt]

Hi, Is it normal that once the panel resumes from idle (short or long - it does not matter in my case) the screen is unresponsive for 2-3 seconds? I tried more complex setups (3 tabs, each with some controls like image, buttons, slider) and simple one (one screen with one button) and the behavior is the same - there is always initial delay.

tried disabling mdns, telnet, mqtt - no improvement

version: 0.7.0-rc13
board: m5stack core2 v1
config: (changes from default)
wifi and mqtt configured
...
"telnet": {
"enable": 0,
...
"mdns": {
"enable": 0
...
"gui": {
"idle1": 10,
"idle2": 120,

scripts:
idle_short.cmd: backlight {"state":"off"}
idle_off.cmd: backlight {"state":"on"}

Below are test results to measure delay from touch to first reaction based on serial log for v0.7.0-rc13 and v0.6.3 with very similar results (2-3s delay) however the screen wake up is little quicker on v0.7.0 making the delay actually more noticeable as there is more time to try pressing something compared to v0.6.3 where the initial blank screen after first touch lasts longer.

It looks like MQTT PUB takes about a second or so.

0.7.0 (with screen dimming via idle_short.cmd with no idle_off.cmd as the screen turns on properly on first touch )

WIP: commenting out brightness-related mqtt status messaging and changing haspEverySecond() task execution interval form 1s to 0.1s does not affect initial screen response delay after wake up which is still ~2.3s
