Help with webpage screensaver

Hello there

I have small issue in this great screen saver

GitHub - cwc/web-page-screensaver: Display a web page as your screensaver

first and sometimes second time it dont works (blank page appears and dissappears quickly)
**third time it works well **

lets say i put screensaver setting after 1 minutes
it works perfectly on second or third minute

ANY HELP to fix this?

Regards.
