They don’t play nicely together. Save a render that has lens effects to the History thingy and well… good luck.
Tried the latest nightly as of today, still not working. 
Sorry if someone has already flagged this, did a search but didnt find anything.
Can you be more specific with “good luck” ? 
I tried to save an image with bloom and glare to the history, browse through history images with the lens on/off .. everything seems ok.
sorry for my vague and uninformative message 
high res renders - currently 7k wide. I rendered it with lens effects on, save to history buffer, then go back and load it, and it shows the vraylenseffectssource rather than the rgb element. happens every time.
If you want I can screen share with someone to demonstrate.

Can you send us a sample scene and step-by-step guide how to get the issue here?
I’ve just run a quick test on 7k resolution with version 3.00.08 but I couldn’t reproduce it.
can i send you a .vrimg ? to the support@ email address?
Yes please.
If the file is too big we could provide our FTP server.
