Thanks for your reply. Unfortunately, that is not a solution for my problem. 
When I wrote "updating" I meant "refreshing". I just tested it again. I have a 
layout with 12 pages and 33 different maps, each showing a different view of my 
mapping project. The individual maps show 3 different map themes. Switching 
from map themes to lock layers doesn't change the outcome.

Just opening this layout freezes QGIS for more than 5 minutes. Just scrolling 
through the 12 pages is glacially slow, moving an item is choppy, I need to 
select it and press the mouse button for half a minute before I can start to 
move it. Then another scroll or zoom in the layout will cause another refresh 
and another long wait.

So far I haven't found a way to turn of the refresh. It would be sufficient for 
QGIS to just cache a static low resolution image of the individual map's 
content and only refresh it, when I change the view or manually refresh. In 
it's current state it's unusable for me and I need to come up with a 
workaround for my upcoming 10 similar projects.

Best regards
Toby
