Bug - Text not showing in Full Screen

Having issues with RTF files taking sometime to show when selected in full screen.

At times some files are just showing a middle portion for 5 seconds then the rest shows.

Anyone else having issues.

How big are these files?
Are the RTFD files with embedded objects?

They are extremely small files and they are just basic RTF.

I have noticed that once you run the cursor over the pane, the text shows up.

Which version do you use and could you please post screenshots of Preferences > Editing and of the full screen view? Thanks!
