Smoothing incorrectly disabled when LED status enabled

[Ajwinarski]

• I confirm that this is an issue rather than a question.

Bug report

I have smoothing defaulted to be enabled when LED status is enabled, however, it appears to be on when the LEDs are off and off when the LEDs are on. Smoothing section of the config.json is as follows:
"smoothing": { "decay": 1, "dithering": false, "enable": true, "interpolationRate": 25, "time_ms": 150, "type": "linear", "updateDelay": 0, "updateFrequency": 25 }

Gif of bug shown here.

Steps to reproduce

Toggling the LED status. Monitoring the status of smoothing.

What is expected?

Smoothing should be enabled by default.

What is actually happening?

Smoothing is turned off when LEDs turn on.

Would you mind sharing a debug log, please?

• Activate Debug log via System-Log
• Disable the LED instance and Enable the instance to trigger the issue described above
• Share the Debug log and config via System-Log->Copy log to clipboard

Lines 2048 and 2071 from the config file show that ComponentRegister.cpp:89:setNewComponentState() is enabling smoothing after the TV LEDs are turned off and vice versa when turned on.

Thank you for the Log.

Line 2048 enables Smoothing, as a background effect is started with smoothing configured

Line 2071 disables Smoothing, as the background effect is stopped because the V4L input took priority

Seems I need to check, why the background effects kicks in when the instance is disabled.

Do you remember how you triggered
2024-03-04T02:15:01.058Z [COMPONENTREG|TV Leds] (DEBUG) (ComponentRegister.cpp:114:handleCompStateChangeRequestAll()) Disable Hyperion instance, store current components' state

Via the Suspend or the Idle command? I assume Suspend...
