Dopus caused blank icon (white icon) during windows 10 startup

when win10 startup very early stage, the icons appear nomormally, but after a system screen refresh, the icons are changed to blank or white icons. when I uninstall Dopus, and restart the computor, the Icon display no problem.

I tried to delete the IconCache.db file, and restart the computor, it sometimes works, but the problem jumped out frequently.

thanks very much!

Which icons do you mean?

What is a “system screen refresh”?
