I am working in layout with multiple detail views. Sometimes suddenly when i pan away contents of a detail view go missing and its impossible to restore because no command has been called. Undo doesnot work. It happens when i hold right mouse button and move the screen and suddenly it dissapears.
It is annoying and i cant think of a cause.
this is the file right after it dissapeared. try to go to layout and inspect the detail view compared to others which are the same in terms of view, maybe by finding out in what view missing detail view is at it will tell more whats going on.
Hello - your objects are quite far from the origin - less than a million units but still pretty large numbers - and there are three text objects right near the world origin - my guess of the moment is this is making the extents of the scene large enough to mess with the display - I’ll poke at it some more.
I found this: If I delete the text near the world origin, I can zoom extents in that top left detail then set the view scale 1:0.1 as in the other details and it looks right - almost: one dimension goes haywire, I am not sure what that is about but I will get it on the bug list.

Does that help you at all?
My solution so far is to lock those views. Maybe during an hour of work i did not encounter this issue when detail views were locked. I will tell if it keeps happening even with locked views.
In my other model there were no objects close to origin and it happened even in that other model. So it may be related to far from origin but it is probably not connected to objects which are close to 0.
Right now i know it always happened when detail views were not active and there was no other action than panning and scrolling in layout, so basically no manipulation of any objects. So since just scrolling mouse wheel can trigger this this will definitely be very exotic type of bug. I have ruled out Single-event upset - Wikipedia so far since it repeated more times in a day. I am not that lucky.
