Fails when screen off - Backlight.DLL failure

[osamz]

Hi, from many months ago I saw that Rainmeter fails suddenly when my screen off (or randomly sometimes), when time-out only, not happen when I power off it manually by button.
I use Desktop Acer Monitor, with GTX 1050Ti

This is an fault in Backlight.DLL as I understand from Event Viewer.

Finally, these some lines which may indicate problem source, from Rainmeter log

Note: rainmeter log file is not saved when it crashed, so every time I run Rainmeter, log file starts-over.

I hope this can be fixed.

I also faced this issue but managed to fix this error by editing the skin file so that the skin only update by User input
Here is my edited Brightness_Small.ini: (remember to change the file extension though
Brightness_Small.txt

@XBachs
It's now works great, but I want to apply same thing on other variation, can you explain to me what you did?

[XBachs]

The Rainmeter crash because the brightness skin update in event when screen turn on or when you using your desktop Monitor's UI ( to change monitor setting via physical monitor's button or similar). So, the easy solution is edit the skin so that it won't update when mentioned event occur.

Firstly change UpdateDivider setting so that the skin won't auto update

in [Rainmeter] measure, add or change value;

DefaultUpdateDivider=-1

in [MeasureBrightness] measure, add or change value:

UpdateDivider=-1

Secondly change Mouse scroll action in [Round] measure so that the skin will update on Mouse scroll

in [Round] measue, replace your original lines with my below edited lines:

MouseScrollUpAction=[!CommandMeasure MeasureBrightness "ChangeBacklight +#BrightnessScrollIncrement#"][!UpdateMeasure MeasureBrightness][!UpdateMeter "Round"][!Redraw] MouseScrollDownAction=[!CommandMeasure MeasureBrightness "ChangeBacklight -#BrightnessScrollIncrement#"][!UpdateMeasure MeasureBrightness][!UpdateMeter "Round"][!Redraw]

the change in my edited lines are :

replace original [!Update] with [!UpdateMeasure MeasureBrightness]

you can read the difference between those two in Rainmeter manual in their website
