Blinkig property of boolean custom control

[bienieck]

Hi, 

I would like to create a custom boolean control (I need a control which looks like modern square LED but in shape of a frame) and preserve blinking property. How to do this trick? Do in need to unlock some hidden feature like "enableSecretPopups=True" in ini file?

All my attempts end up with barely visible blinking in a form of some kind of "shadow"...

Thanks in advance 🙂

Only some parts of the control blink, so you should make sure to resize the correct parts when in the control editor. can you attach your example control?

I used some random frames from Google, for now. See the attachment.
