Amazfit Watch faces

Here you have:
- my BIN
- the GIF created by watchface.exe from json compilation
- the extracted first image from GIF
- a photo of my MI Band 5 with this watch face
DelimiterImage.zip

As you can see, the progress bar background and date delimiter point are visible on MI Band, but not in the ...

I can't get 2 small animations running at different speeds on the MI Band 5.
Both always run at the slower speed.
If I put both of them on the fast speed, they'll both run fast.
Is this a firmware bug or could it be that MiBandWFTool does not write the parameters correctly into the .bin file?

There are no stock watchfaces with 2 different animation speeds.

Could you fix the "DelimiterImage" preview bug ?

I want to show here all known MB5 firmware bugs concerning custom WFs:
- 2 or more animations are always running with the speed of the slower one
- Seconds are not really working (analog and digital)
- UVI and wind are not working together with other weather features (current temperature)

"Text": OK
"ImageOn": OK
"ImageOff": OK
"ImageNoAlarm": The red line in my example should start at X=0 and Y=17, but starts at the position defined in "Text"

On MB5 all works like expected.

Next preview bug:
"StepsProgress": - "CircleScale":
MB5 stops drawing the progress bar if "EndAngle" is reached, preview drawes around...

Suggestion for improvement:
The display of the MB5 has rounded corners.
It would be nice if the corresponding pixels were also set to black in the preview.
