It is a known issue , see

Maybe somebody know how usé ffmpg to send desktop without lag to Chromecast
(my quick test (from the first result on Google/duckeuckgo) was not ok)?

A hipotetical solution would be record Desktop with ffmpeg, use sometype of
proxy to play the recording on a localhost http URL which could be played
from chromium and then send the tab to chromecast
