I'm receiving a screen flicker (quick flash of white) with every page load with 5.4.2.2 when logged in as a user with edit capabilities. When logged out this doesn't occur. The sites are functioning accordingly, but it'd be great if this weren't happening.

This didn't happen in 5.4.1 and I'm curious if there is something funny going on or anything changed that could be making this happen.

Can someone help?

All the best,

Tim
